3.3.5 X14 Trigger Input Connector

The Trigger input connection to the J-Panel is connector X14. The connections are listed in Table 7

TABLE 7. Trigger input connector.

3.3.5 (a) Trigger polarity

The switches S3 and S5 sets the trigger polarity:

If the trigger signal is normally low

(no voltage at trigger input) the switch shall be in position

Arrow up - positive going

If the trigger signal is normally high

(voltage at trigger input) the switch shall be in position

Arrow down – negative going

As a guideline the two LEDs marked TRIG-0 and TRIG-1 shall be off when no trigger pulse is present.

3.3.5 (b) Test Trigger

Activating switches S1 and S4 generates a trigger pulse for test purposes. Only one trigger pulse is

generated each time the switch is activated.

The duration of the trigger pulse is approximately 4 ms.

The trigger indicator LEDs flash when the test trigger switch is activated.
