1 ISTSG REV 00.01

To program the STOP input:

4. Set the dip switches as shown

1 2 3 4 5 6 7 8 9 10 11 12

5. Execute the "save procedure" (heading 4.4), which in this case is required to save the status of the STOP

input in teach-in mode.

6. Return the dip switches to the setting indicated

1 2 3 4 5 6 7 8 9 10 11 12

Note. When the programming procedure is terminated the STOP LED must remain illuminated to confirm that the data have been saved correctly.

16.9 Phototest

The Phototest function is an ideal solution in terms of reliability in relation to safety devices and it makes it possible to achieve "category 2" in compliance with UNI EN 954-1 (edition 12/1998), in relation to the combination of control unit and safety devices. To implement this solution connect the photocells as shown in the following diagram and set dip switch 7 to On (Phototest activation).

Whenever a manoeuvre is started all the safety devices are tested and the manoeuvre is effectively started only when the test gives positive results.

16.10 Checking the connections.

The following operations involve work being carried out on live circuits. Some parts carry mains voltage and are therefore extremely dangerous! Pay maximum attention to what you are doing and never work alone!

When you have finished making the connections it is good practice to perform a general check as follows:

• Power on the control unit and immediately check for the presence of mains voltage on terminals 1-2 and between 28 and 33 volts on terminals 9-10 (services output). If the values do not correspond to the above specifications, disconnect the unit immediately and check the connections and power supply voltage carefully.

• Approximately 2 seconds after power-on the OK LED should start flashing at regular intervals of one second to indicate that the control unit is functioning correctly.

• Check that the LEDs relative to the STOP and Photo inputs are illuminated (safety devices active), while the LEDs relative to the step-by-step and open/close inputs must be extinguished (no command present); if this is not the case check the connections and ensure that the various devices are functioning correctly

• Check that all the safety devices in the system are functioning correctly (emergency stop, photocells, pneumatic safety edges, etc.); whenever the safety devices trip the relative STOP and Photo LEDs must switch off.

• Release the barrier and check that: the bar is balanced – if it is not, adjust the balancing spring the bar is free to move without undue resistance throughout the entire range of motion the limit switches are functioning correctly: with the bar closed only the closed limit switch LED
