Configuration
The following configurations are possible through controller or configuration tool:
l
After activating the output remains:
‒
Steady output
‒
Pulse output: How long the contact remains active can be configured by controller or
configuration tools (pulse duration).
l
Failsafe behavior when the FD18-BUS detector line is current-free or in degraded mode.
The error behavior defines the position of the output in case of an error:
‒
Off: Output remains in the same position as before the error
‒
Activation: Output is activated in case of an error
‒
Deactivation: Output is deactivated in case of an error
The controller does not monitor external equipment status (activated/inactivated).
Inverted operation (output lines not monitored)
-
Be used for controlling (e.g. closing a door).
-
The module switches the externally supplied 24 V DC voltage in active status on the
output.
-
In normal status there is no monitoring for open line and short circuit.
-
The jumper on the input/output module must be plugged onto J2/J4 (Fig. 4).

Fig. 5 Connection diagram for inverted operation, e.g. when used as door retainer.
In inactive status the 24 V DC are permanently applied to the output and may keep a door
open, for example. When the output is switched to active, the output goes into "open" status
(= no 24 V DC voltage) and the door is closed.
Comment:
In this example, the door would also close if the 24 VDC supply were to fail, e.g. due to a line
problem (short circuit, open line).
