2.5.2 Alarm module
The alarm module contains
❑ 3 binary outputs and
❑ 1 binary input
The binary outputs are used to output fault signals and alarms. Config-
uration is described in Section 4.4 parameters 30 to 35.
An external signal at the binary input (BE2) can cause the actuator ei-
ther to be blocked or put in its final position, depending on the configu-
ration.
The alarm module is available in two versions
❑ Ex–proof for connection to switching amplifiers to
DIN 19234
❑ Not ex–proof for connection to voltage sources of max. 35 V
The semiconductor outputs of the alarm module output an alarm (signal
state low) by switching to high resistance. In the high state (no alarm)
they are conductive. Dynamic control makes them self annunciating.
The outputs are isolated from the basic circuit and from each other.
The binary output is double:
❑ Isolated for voltage level
❑ Non–isolated for floating contacts
These two inputs are implemented as a logical OR operation.
The alarm module is slotted into the rack under the motherboard as far
as it will go and connected to the motherboard via an 8–core ribbon
cable (5), which is supplied (see Fig. 2-12).
2.5.3 Jy module
The J
y
module is used to output the current position of the actuator as
a 2–wire signal 4 to 20 mA.
The current output is isolated from the basic circuit.
The J
y
module is inserted into the slot of the rack as far as it will go and
connected to the motherboard using the 6–core ribbon cable (6) sup-
plied (see Fig. 2-12).
