Operating your Gemini R or Pro

The Bowens Gemini R and Pro monolights can be operated fromeither an AC (mains) supply or from a Bowens Travelpak battery.

For AC (mains) operation, the AC switch (page 4) should be in the upper position.
For DC (battery) operation, the switch should be in the lower position.

NOTE: When operating from a Travelpak battery, the modelling functions are not available, this is to preserve battery life.

• Ensure the power source if off.
• Connect the unit using the appropriate cable.
• If using the Travelpak, ensure the connector locks are fully tightened.
• Switch the power source on, then switch on the Gemini.
• The unit will charge & indicate it is ready for use by lighting the green flash-ready LED.
• Press the test button to check the unit fires.

WARNING HIGH VOLTAGE! Never connect a Gemini monolight to a Travelpak battery and AC (Mains) supply at the same time. This appliance must be grounded when used with AC. Disconnect the AC plug when changing modelling lamps and flash tubes.

Mounting your Gemini R or Pro

Mount your monolight on a dependable support system.

The mount bush on the ‘L’ bracket allows for two possible ways of mounting to the stand/support (below).

Method B may be found useful if the light is required to point down.

User Set-Up Options

To enter the ‘user set-up options’ hold down the ‘flash test’ button (page 4) for 3-4 seconds when the unit is switched on.

Once the unit has entered the user set-up options the LED display will first show a continuous sequence of numbers (four sets of two numbers). Firstly the software version will be displayed (shown by a decimal point i.e. ‘1.1’), followed by a three, two-digit number sequence, representing the total flash count for that particular unit (up to 999,999). Each set of numbers in the flash count sequence will be interspersed with a dash, for instance 00-15-76 (representing 001,576 flashes).

Once the LED display had cycled through the software version and the total flash count, the unit will then activate the ‘user set-up options’.

The ‘1/10-stop (TENTHS) power adjust dial’ is used to select the required function / option for review or change.

Once a user set-up option is selected using the TENTHS dial, the LED display will show the current setting.

To cycle through / change the setting for any user set-up option, press the ‘modelling lamp function switch’ (page 4) at the rear of the unit either up or down.

Once all the user set-up options have been reviewed or changed as required, press the ‘flash test’ button to save the amended settings and reboot the unit to normal operation.

Mains / Battery Voltage Supply

The Gemini R range is a single / fixed voltage unit (117V or 230V) and will only operate from a fixed mains (AC) supply (either 117V or 230V); or via one of Bowens battery systems. Always check the supply voltage for each unit before using.

The recommended voltage supply for each unit is stated on the rear panel just below the mains connection (page 4). To use the Gemini from a mains supply the ‘mains / battery power switch’ (page 4) must be in the upper position.

The Gemini Pro range units are all multi-voltage and will operate from a nominal 117V or 230V mains power supply (as well as from one of Bowens battery systems), once a mains power supply is connected to a Gemini Pro and the unit is switched on, the unit will automatically detect the voltage supply it is connected to.

The battery (DC) input from a Bowens battery system is automatically detected when connected and the unit switched on. To use the Gemini from a battery system the‘mains / battery power switch’ (page 4) must be in the lower position.

Flash Power Control

The flash power is set using two rotary dials (fig.1); the lefthand dial is used to increase or decrease the flash power in full 1-stop adjustments, the right-hand dial is used to control the power in exact 1 ⁄10th-stop adjustments. Both settings are indicated on a scale around each dial; the current setting isalso shown on the LED display.

The maximum F-stop (power setting) depends on the flash power rating of each individual unit. 250Ws, 500Ws and 750Ws units provide a 5-stop power range, F1.0 to F6.0 (5- stop power adjustments over 6-stop points is equal to full power to 1⁄32). The 1000Ws and the 1500Ws units provide a 7- stop range, F1.0 to F8.0 (7-stop power adjustments over 8- stop points is equal to full power to 1 ⁄128).

Infra-Red Remote Control Power Adjustments

The first position (REM) on the 1-stop power adjust dial sets the unit to operate from Infra-Red remote control only. Once the unit is set to operate from IR remote control the power setting can then only be read from the LED display, as the power adjust dials will not function.

Once the unit is in remote control mode, the 1 ⁄10th-stop power adjustment dial selects the prefered remote control channel:

position 0 (0.0 tenths) = All channels,
position 1 (0.1 tenths) = channel 1,
position 2 (0.2 tenths) = channel 2,
position 3 (0.3 tenths) = channel 3,
position 4 (0.4 tenths) = channel 4 etc.

The IR channel can be adjusted at any time once the unit is in remote mode (REM).

Automatic Flash Dump

Automatic flash dump (as well as standard resistive dump) can be selected during the ‘user set-up’ mode, which is available when the unit is switched on (see page 5 for ‘user set-up’ mode and options).

Automatic flash dump is a built-in feature of the Gemini R and Pro level models. The Gemini’s intelligent management system controls the automatic flash dump function by monitoring the difference between the current, set flash power level, and the target power the unit has just been adjusted to. The management system decides if it would be quicker for the unit to flash dump the power and recharge to the desired level or to simply resistive dump the power to the required level. The automatic flash dump only works 1-2 seconds after the user has stopped adjusting the flash power.

Note: When turning a Gemini R or Pro off, the unit will automatically dump the charged power, this is to ensure that no flash power is stored in the capacitors while the unit is switched off.

Power Charging / Dumping Indicators

The illuminated ‘flash test’ button on the side of the unit (see page 4) shows the charging status as follows:

Charging – Green LED flashes quickly
Ready – Green LED lit continuously
Dumping – Green LED flashes slowly

Flash Ready Indicators

There are various indications available on the unit to let the user know when the unit is 100% charged and ready to fire.

Ready Sounder – an audible ready beep is available via an on / off rocker switch at the rear of the unit (see page 4); the ready beep can also be switched on / off from a remote control (only in REM mode).

The ready sounder can be used in two ways; the user can set the ready sounder to either emit a continuous beep while theunit is charging and go off when it is 100% ready, or the unit can be set to emit a short beep when the unit is charged and 100% ready. The ready sounder options can be set during ‘user set- up’ mode. See page 5 for user set-up mode instructions.

Modelling Lamp Ready Indications – the modelling lamp can be used as an indication as to when the unit has fully charged and is ready to fire. The modelling lamp can be set to ‘intermittent’ or ‘pulse’. When the modelling is set to intermittent the lamp will extinguish when the unit has fired,and illuminate again after the unit has charged and is 100% ready. The modelling lamp ‘ready’ indication settings can be adjusted during the ‘user set-up’ mode.

If the modelling ready indication is set to pulse, the lamp will simply pulse during the recharge state and come back to the current setting once the unit has charged and is 100% ready. In pulse mode, if the modelling lamp is set to a low level when the unit is fired the modelling will increase in brightness / output during the recharge state and then lower again to the current setting when the unit has charged and is 100% ready. If the modelling is set to a high level when in pulse mode, the modelling will decrease in brightness / output once the unithas been fired and will increase again to the current setting once the unit has charged and is 100% ready.

operation

Modelling Lamp Control

The modelling lamp on the Gemini range has a soft on and off feature to prolong the life of the bulb.

There are various options available on the Gemini R and Pro range models to control the modelling output. Thesefunctions can be set using the centre biased modelling lamp function switch on the rear of the unit (page 4). To change the lamp output option, simply cycle through, either up or down.

The various output control options on the R and Pro range Gemini’s are:

1. Relative (REL) – to control the modelling output in proportion to the flash output – when the flash output is altered, the modelling lamp will automatically adjust itself in proportional to the desired flash power level.
2. User (USR) – allows the user to manually set the modelling to the desired output.
3. Max (MAX) – sets the modelling output to maximum.
4. Off – the modelling lamp will completely switch off.

The various modelling lamp control options are highlighted by individual red LED’s on the side and rear of the unit (page 4.) When the modelling lamp is set is set to ‘Off’, none of the red LED’s will show.

The red LED’s on the side and rear of the unit will display the various options as follows:

Relative – REL LED lit continuously.
User – USR LED lit continuously.
User set – USR LED flashes.
Max – MAX LED lit continuously.

Manually Setting the Modelling Output

The modelling lamp output can be adjusted manually.

To manually set the modelling output change the modelling option to the User (USR) setting by using the modelling lamp function switch. When the User option is active the USR LED will flash quickly and then stay on continuously.

Once active the modelling output can then be adjusted by using the modelling lamp function switch, pressing up to increase and down to decrease the output setting.

Setting the Modelling Output with IR Remote

The modelling output can also be set manually by using a remote control. To set the modelling output option to User (USR) using a remote control, press the ‘Lamp On/Off’ button on the remote control. Once the User option is selected and active, press the ‘Master + / -’ button on the remote control to adjust the output.

When setting the modelling lamp output the 7-segment LED display on the side of the unit (page 4) will show the current or desired output level.

Lamp Saver Mode

The modelling lamp on the Gemini R and Pro range features a ‘lamp saver’ function; this allows the modelling lamp to dim if no adjustments are made or the unit hasn’t flashed for a specified amount of time.

The length of time for the ‘lamp saver’ function to activate can be set from 1 to 99 minutes in ‘user set-up’ mode (see page 5 for ‘user set-up’ mode and options).

Photocell

The Photocell is a built-in light sensitive trigger that allows the unit to be fired from an external flash source.

The ‘CELL’ switch on the rear of the unit (see page 4) allows the Photocell to be switched on or off.

If the switch is set to the ‘lower’ position the cell will be turned ‘on’, setting the switch to the ‘upper’ position will turn the Photocell ‘off’.

Triggering Using External Flash – To trigger the Gemini using an external flash source the Photocell must be switch on. If the photographer is using an external flash source that uses pre-exposure flashes (like a small on-camera flash) the Photocell must be set to the ‘Smartcell’ function in order to sync with the camera.

Smartcell – the Photocell on the Gemini R and Pro range has a ‘smartcell’ option to enable pre-exposure flashes to be ignored. These can be used for exposure measurement and/or red eye reduction. This option allows the Gemini to be synchronised to the camera shutter on the 1st, 2nd, 3rd or 4th flash selected by the user (this option is for those who wish to trigger theIr flash heads without a radio or IR triggering system or without a sync cable). A recognised 1st flash is the normal ‘instant’ trigger, where only one flash is used coincident with the shutter. To set the desired number of recognised flashes to sync the unit with, the Gemini must bein ‘User set-up’ mode (see page 5 for ‘user set-up’ mode and options).

Smartcell ‘Learn’ mode

The ‘smartcell’ can also ‘learn’ the trigger sequence of the external flash so the number of pre-flashes does not have to be manually set. For the Gemini to learn the pre-flash sequence the user must enter the ‘User set-up’ mode and select the Photocell Trigger option. Once the Photocell Trigger option is selected red LED’s on the side and rear of the unit will flash continuously. The Photocell Trigger option on the Gemini must then be set to the 1st flash to enter the learn mode; when number 1 is highlighted / shown on the 7- segment display, aim the external flash at the Photocell and fire the flash. The Photocell will monitor the flash and learn the sequence / number of flashes. The total number of flashes detected will then be shown on the 7-segment LED display on the side of the unit. After the number of flashes is displayed press the flash test button to save the setting shown and to enter normal operation.

Triggering Options

There are a number of ways to trigger the Gemini R and Pro monolights:

Open Flash – For testing or multiple flash applications the ‘Test Flash’ button can be used.

Sync Socket – The standard 1 ⁄4” jack socket on the rear panel of the unit may be used for direct connection to a camera or trigger system (i.e. radio or IR

Photocell – The Gemini has a built-in switchable (on/off) photocell enabling the unit to be triggered by an external flash source.

Plug-in Radio Trigger – The Gemini R and Pro range models feature an option to include a plugin radio trigger module.

Plug-in Radio Trigger Module

The Gemini R and Pro models feature a unique option to include a plug-in radio trigger module. There are three different plug-in modules available (sold separately) for various professional radio triggering systems, depending on which one the user may already have or wish to use. The three different plug- in trigger modules that are available for the Gemini R and Pro range are:

• Bowens Pulsar Radio Trigger System.
• PocketWizard Radio Trigger System (344Mhz and 433Mhz modules available).

Changing the Modelling Lamp

Switch off the Gemini and disconnect from the power supply. If the unit has been in use, allow a sufficient amount of time for the lamp to cool.
Unscrew the modelling lamp from the lamp housing and replace wit hthe correct lamp type.

When changing the modelling lamp on a Gemini 1000Pro or 1500Pro, first remove the protective glass cover over the flash tube (ensure the glass has cooled sufficiently before touching if the unit has been in use), then replace the modelling lamp.When changing the smaller E11 Halogen lamps, ensure not to touch the glass with your fingers as the oils from your hands can reduce the life of the lamp.

Changing the Fuse

The modelling and flash circuitry are protected by a single 20mm fuse mounted in the rear panel of the unit.

A fuse may blow when the modelling lamp fails; always check the fuse when replacing a bulb. A spare fuse is located in the draw underneath the mains connection at the rear of the unit. The fuse draw contains two fuses, the furthest fuse inside the draw is the live fuse and the nearest one is a spare. Never replace the fuse with one of a different rating.

Always switch off the unit and disconnect the power supply before changing a fuse.

Transporting Units

When transporting any Bowens units, ensure that all equipment is carefully packed into appropriate bags and/or hard shell cases. Make sure all items are securely placed inside the appropriate baggage to protect from any knocks.

Flash units can become very hot after use. Always wait a minimum of 30 minutes before packing to allow units to cool sufficiently.

If a unit is dropped and / or knocked during transport, always have the unit checked by an authorised Bowens service / repair centre before using.

Power Cables

Only use Bowens approved mains or battery cables to power Bowens products. All mains cables must be used as appropriate to the flash units rated power voltage, and the correct mains pin-configuration.

Warranty

All Bowens electrical products are covered by a two year warranty against any faulty design, materials and workmanship.

If a product does not work on arrival or up to a maximum period of four weeks from the date of purchase, it should be returned to the dealer/retail outlet from where it was purchased, to exchange (if available) the faulty unit for a new one; if the faulty unit was part of a  kit that was purchased, the dealer / retailer may choose to simplyreplace the unit and not the entire kit. Alternatively the dealer may offer to repair the unit as soon as possible at no charge.

If neither an exchange or repair is possible for the faulty unit, then a full refund may be made.

If a warranty fault occurs after the initial four week period (and within the max two year warranty period), then the unit should be returned to the dealer, who will arrange to repair the unit as soon as possible, at no charge.

This warranty does not apply to consumable items such as flash tubes, modelling lamps, fuses, consumable type batteries.

Should a unit be returned at any time within the two year warranty period, and it is judged to have experienced any of the following points, failure to follow working instructions correctly, accidental or willful damage, misuse, alteration or repair by a non authorised Bowens service / repair centre, then the warranty will be deemed invalid and any repairs that may need carrying out will be payable by the owner.

The cost of any repairs should be notified to the owner, by the dealer, in advance of undertaking any work that may be required.

No warranty repairs can be undertaken to any units without proof of purchase.

All warranty repairs or returns must be conducted with the dealer from where the product was purchased.

Other terms and conditions may be applicable in specific countries, if stated by the dealer at the time of purchase.
