INSTRUCTIONS FOR USE

C lamping, turning on and focusing

Zoom Revolver must be mounted on a rigid support by means of adequate clamps. Specifically it must be constrained in the spaces labelled as “clamping diameter”. Clamping the product in other positions might seriously damage internal components and alter the overall optical performance.
Use the CMHOTCZR mechanical clamp for safer and accurate mounting. CMHOTCZR also allows greater freedom in mounting.

Turn on the product by connecting the power supply cable to a 24V direct current source. When you turn on the device, it emits a specific acoustic signal (trill / “trillo”) and the first available magnification position is automatically selected. If a magnification position is already selected, the device will only emit the acoustic signal (trill) without any rotation of the carousel.
The device should always emit the characteristic acoustic signal (trill). If this is not the case, please contact the seller.

After clamping and turning on the device, please follow step by step the focusing procedure explained below:

1. Adjust the WD until it is equal to the WD value listed on the test report you received with your Zoom Revolver.

2. Set the maximum magnification position by rotating the carousel until you reach the maximum magnification position;

3. Precisely adjust the mount position by means of adding/removing back focal adjustment spacers until you find the best focusing position.

4. Adjust the phase angle. Once you find the right phase, lock the screws.

5. Accurately adjust the focus by using the bush positioned at the front of the objective.

How to change magnification

Zoom Revolver offers two ways to change magnification:

• “Stand alone” mode by pressing the button;
• On-line mode by DLL.

Magnification change by pressing the button

When used in “stand alone” mode, Zoom Revolver is not connected to a PC: change magnification by simply pressing the blue magnification button located below the LED position indicators. Just press the button until you reach the desired magnification position (the corresponding LED position indicator will show the position): after a few seconds the carousel will rotate until it reaches the selected position and the corresponding LED position indicator will turn green.

In case of failure of the procedure defined above, connect the TCZR to a PC and proceed as described in paragraph 5.2.3.

Magnification change by DLL

On-line mode magnification change requires the following system specification:

• 512 MB RAM;
• 1.5 MB free hard disk space;
• XGA or higher-resolution monitor;
• Mouse or other pointing device;
• Intel® Pentium® III/M 1.4 GHz Processor minimum;
• Operating System 32 bit:
  • Microsoft® Windows XP Home or Professional (SP2);
  • Microsoft® Windows Vista (requires Administrator rights);
  • Microsoft® Windows 7 (requires Administrator rights).

You additionally need to implement a DLL that resembles the following DLL Function prototypes.

Alarms, errors and solutions

In case of failure, TCZR must be connected to a PC in order to visualize the error type.

Once your Zoom Revolver is connected to the PC, call the *Get State function to get the error type. You can subsequently visualize the device state, in particular:

• Position : return the current position of the device
• Error Over Supply : return 1 if supply voltage (Vin) is too high, otherwise 0
• Error Under Supply : return 1 if supply voltage (Vin) is too low, otherwise 0
• Error Over Current : return 1 if coil current is too high (over Imax), otherwise 0
• Error I2T : return 1 if I2T error, otherwise 0
• Error Position : return 1 if position not reached, otherwise 0
• Warning Position : return 1 if position reached with more steps than Step Pulse, otherwise 0
• Step Done : return to the steps performed to reach the position
• Busy : return 1 if the device is busy, otherwise 0
• Run : return 1 if the device is moving, otherwise 0

In case of:

• Error Over Supply
  Error Under Supply

• Error Over Current

Adjust the system’s power supply. If that is not the cause of the failure, contact the seller.
State “ErrorI2T” is a self-protective condition of the system: the device stops working and then automatically re-starts after a certain amount of time. In case of “ErroreI2T” keep monitoring error state and wait for system recovery. Contact the seller if the system does not re-start correctly.
In case of Error Position call the DLL *Trillo or reboot the system. If the problem persists contact the seller.

SOFTWARE DEMO

Run the executable file (setup.exe) to start software installation.

DEMO mode Control Panel

TCZR control panel consists of 5 sections:

• Ports
• Parameters
• Versions
• Device Status
• Commands

In section Ports press the OPEN button to connect your TCZR to the PC. The “Common Port” window shows the virtual serial port number where the device is found. Three state coloured indicators show state messages: the system is correctly connected if the Connected indicator turns green while Timeout and Checksum are error messages.

In section Parameters, the default factory settings are listed. Press the “GET” button to update and get the present values. Press the padlock button and type the password to enter the “Advanced Mode”.
Section Versions lists the DLL release and firmware version.
In the Device Status Section, the following error, warning and state indicators are listed.
In detail:

• Over supply error(see 5.2.3);
• Under supply error(see 5.2.3);
• Over current error(see 5.2.3);
• I2T error
• Position Error (see 5.2.3);
• Position warning (see 5.2.3);
• Busy (see 5.2.3);
• Run (see 5.2.3).

Commands section allows the user to set the Zoom Revolver magnification by selecting the corresponding position (0,1,2,3). In case of position Error, press the “Trillo” button to recover the position.
