Alarm Outputs
G1038Z0
figure 4-12 Alarm outputs (optocoupler)
figure 4-13 Flange connector, 7 poles
The alarm outputs (pins 1 to 4: output with pull-up resistor 5 V / 1 mA; see figure
4-13) are normally low. In case of an alarm they are high active (5 V). They can be
used to monitor alarms with an external alarm indicator.
The +28 V pin (pin 6&7) is specified to 28 VDC / 0.5 A and is protected by a
thermoswitch. In case of exceeding this current between pin 7 and GND, the
thermoswitch turns into a high-resistive status. In this case no fuse needs to be
replaced. Just wait a few minutes until the thermoswitch reaches the normal
operating temperature again.
 Note: The manufacturer / supplier of this system assumes no liability for
damage caused by equipment connected to external outputs or by
effects from such equipment.
