UNPACKING THE Optical Sensor Switch

1.1 Inspect Package for External Damage
Your Optical Sensor Switch was carefully packed in a sturdy cardboard carton, with anti-static cushioning materials to withstand shipping shock. Upon receipt, inspect the package for possible external damage. In case of external damage to the package contact the shipping company immediately.
1.2 Unpack the Optical Sensor Switch
Open the carton carefully from the top and inspect for any sign of concealed ship- ping damage. Please keep all packing and notify Omega Customer Service of any damage.
When unpacking the instrument please make sure that you have all the items indicated on the Packing List. Please report any shortages promptly.

1.4 Returning Merchandise for Repair
Please contact the customer service representative at 1-800-826-6342 ext. 2208 for a Return Authorization Number (AR).
It is mandatory that any equipment returned for servicing be purged and neutralized of any dangerous contents including but not limited to toxic, bacterially infectious, corrosive or radioactive substances.

DESCRIPTION

The 150 mm Flow Meter with Hi-Lo Alarm Optical Sensor Switche is a noninvasive means for detection of a HI or LOW flow.
This sensor is ideal for signaling an alarm, cutoff valve, or other device when the float passes the detector.
The Hi-Lo Optical Sensor Switch consists of the OSSM module and two self- contained mini-slim photoelectric sensors (Thrubeam type). Every sensor has a transmitter and receiver. Two sets of sensors are mounted on two solid carriers on opposite sides of the flow tube. The float inside the flow tube is detected as it passes across the beam of light. The sensors can be used to detect the float passage beyond the set point of the sensor and can also be set to mo111
Pagenitor the float position at a specific level, signaling when the float is outside of the range of the sensor light beam.

INSTALLATION

Electrical Connections

The Optical Sensor Switch gets a power through the OSSM module.
The module could be powered up either by a +12+15 VDC power supply with a minimum current rating of 250 mA, or by the 9-pin D-connector (DB9M) (Fig. 1) for momentary or latch operations.

SUPPLYING DC POWER TO THE POWERJACK AND THE “D” CONNECTOR AT THE SAME TIME WILL DAMAGE THE METER. DC POWER JACK POLARITY IS CENTER POSITIVE.
WARNING: DO NOT CONNECT POWER SUPPLY WITH MORE THAN 15VDC VOLTAGE

3.1. Insert the LOW flow sensor’s plugs into the splitter, then the splitter’s plug into the module’s phone jack #1 (Fig. 1).
3.2. Insert the HIGH flow sensor’s plugs into the splitter, then the splitter’s plug into the module’s phone jack #2 (Fig. 1).
3.3 Connect the power supply through the power jack (Fig. 1). Or
Attach the 9-pin D-connector to the module (fig. 1 & 2).

During the initial power up of the Optical Sensor Switch with no flow conditions the red and green LED on the module will be “On”. This is an indication that power is on and the sensors are ready for operation.
Both sensors will have 2 green lights “On” from each side of the flow meter

Important notes:
In general, “D” Connector numbering patterns are standardized. There are, how- ever, some connectors with nonconforming patterns and the numbering sequence on your mating connector may or may not coincide with the numbering sequence shown in our pin configuration table above. It is imperative that you match the appropriate wires in accordance with the correct sequence regardless of the particular numbers displayed on your mating connector.
Make sure power is OFF when connecting or disconnecting any cables in the sys- tem. The power input is protected by a 600 mA (medium time-lag) resettable fuse.
If a shorting condition or polarity reversal occurs, the fuse will cut power to the valve circuit. Disconnect the power to the unit; remove the faulty condition, and reconnect the power.

The fuse will reset once the faulty condition has been removed.
Use of the Optical Sensor Switch in a manner other than that specified in this manual may impair the protection provided by the equipment.

CE Compliance

Any model Optical Sensor Switch bearing a CE marking on it, is in compliance with the below stated test standards currently accepted.

Immunity Standard: EN 55082 1:1992

OPERATING INSTRUCTIONS

6.1. Sensor Alignments
Two sensors’ carriers can be set in any position along the flow meter tube.
WARNING : Do not install the sensors closer than 1/2” (10 mm) from one to another. Doing so may trigger a false alarm condition.

To set up the switches position:
-Loosen the 2 red thumbscrews;
-Slide the switch carrier to the desired position;
-Tighten the thumbscrews.
Stable operation indicator (green LED) turns on with a stable incoming beam and with a stable blocked light. Output indicator (orange LED) turns on when the beam from emitter is blocked by the float.
Each Optical Sensor Switch is shipped from the factory with the sensors aligned and does not require additional adjustment of the focus distance even if the flow tube was replaced or reinstalled (see p. 6.2).

6.2. DIP switch configuration

The DIP switch, located near the 9-pin D-connector can be used to set up custom’s settings separately for High and Low alarm.
In order to activate the sensor’s alarm the corresponding switch has to be installed in the “On” position on the Configuration DIP switch (see Fig. 3). Each sensor (High or Low) can be separately set for Momentary or Latch operation. In addition the Relay and Buzzer can be configured individually.
As an example, if the SW1 is set to “On”: the High flow alarming (latching mode) is active, then the green LED (on left side of the D-connector) and relay will be energized in the LATCH mode. They will stay in the energized state without any conditions (even if the flow rate changes and the sensor have become inactive) until the RESET button is pressed or external RESET TTL signal is applied. If momentary mode is set (DIP switch SW3 is set to “On”) the relay and green LED will be energized only when the High flow sensor is active (Alarm Condition). The same is true for the Buzzer settings.
All Switches “Off” position–Alarm is disabled (LED, Relays and Buzzer).

ALARM DIP SWITCH CONFIGURATION “On”- pressed down “Off’-raised up

HIGH ALARM| LOW ALARM| ACTION WHEN SWITCH IS “ON”
SW1| SW5| LED and Relay are On (LATCH)
SW2| SW6| BUZZER is On (LATCH)

TROUBLESHOOTING

7.1. Common Conditions

Your Optical Sensor Switch was thoroughly checked at numerous quality control points during and after manufacturing and assembly operations. It was carefully packed to prevent damage during shipment. Should you feel that the instrument is not functioning properly please check for the following common conditions first:
Are all cables connected correctly?
Are there any leaks in the installation?
Is the power supply correctly selected according to requirements? When several devices are used a power supply with appropriate current rating should be selected.
Were the connector pinouts matched properly? When interchanging with other manufacturers’ equipment, cables and connectors must be carefully wired for correct pin configurations.
