Ack signal BO 3 Module input state: Acknowledgement

is set to active, the binary output relay can
only be acknowledged if those signals that
initiated the setting are fallen back and the

Signals of the Binary Output Relays on OR- 3AI X
Name Description
BO 1 Signal: Binary Output Relay
BO 2 Signal: Binary Output Relay
BO 3 Signal: Binary Output Relay
DISARMED! Signal: CAUTION! RELAYS DISARMED in order to safely perform
maintenance while eliminating the risk of taking an entire process
off-line. (Note: The Self Supervision Contact cannot be disarmed).
YOU MUST ENSURE that the relays are ARMED AGAIN after
maintenance
Outs forced Signal: The State of at least one Relay Output has been set by
force. That means that the state of at least one Relay is forced
and hence does not show the state of the assigned signals.
LED Configuration
The LEDs can be configured within menu:
[Device Para/LEDs/Group X]
Attention must be paid that there are no overlapping functions due to
double or multiple LED assignment of colours and flashing codes.
If LEDs are parametrized » Latched= active«, they will keep (return into) their
blink code/colour even if there is a break within the power supply.
If LEDs are parametrized » Latched= active«. The LED blink code will also
retain, if the LED is reprogrammed in another way. This applies also if
» Latched is set to ina ctive« . Resetting a LED that has latched a signal will
always require an acknowledgement.
This chapter contains information on the LEDs that are placed on the left
hand of the display (group A).
If your device is also equipped with LEDs on the right hand of the display
(group B), the information in this chapter is valid analogue The only
difference is “group A” and “group B” within the menu paths.
