Motor control unit DCM31
9 / 35
this as an external limit switch. The limit switch behind the terminals is not
displayed.
[Kl.22]+[Kl.23] photoelectric barrier (LS)
Terminal 22 = LS signal input
Terminal 23 = connected earth
- A photoelectric barrier or an electrical safety contact strip with a floating break-
contact element can be connected.
- The function of the input is determined via [M.b4].
- If the input is not used, it must be jumpered with a wire jumper (delivered
condition).
- The switched status is displayed by the yellow LED behind [Kl.22]+[Kl.23].
- During the control unit self-test, the LED briefly flashes.
- The input has a safety function and is monitored by self-tests of the electronics.
- The “close after leaving the photoelectric barrier” function [M.b5] can be triggered
via the photoelectric barrier input.
[Kl.23]+[Kl.24] safety input (SE) for closing edge safety device 8K2 or OSE
Terminal 23 = connected earth
Terminal 24 = SE signal input
- Optional use of a 8K2 safety strip or OSE is possible as a closing edge safety
device.
- The type of strip connected and function of the input are set via [M.b6].
- OSE connection: Kl.9=+12V, Kl.10=earth, Kl.24=signal
- The switched status is displayed via the yellow LED behind [Kl.24].
- If the SE input is not used, the [J1] must be connected to NC [X4] (8k2-resistor is
switched on internally) and [M.B6] set to 8k2 (10) or the SE input deactivated
[M.B6] = 00.
- If a closing edge safety device is connected, [J1] must be connected to SE [X4].
- This input has a safety function and is monitored by self-tests of the electronics.
[Kl.25]+[Kl.26] input A (pulse / open)
- Input for pushbutton, key-operated switch, external radio, etc.
- The controls must have a floating contact, which is open in the idle condition (make
contact).
- Several pushbuttons, etc. can be connected in parallel.
- The input is connected internally parallel to the slot of the radio receiver ([Bl.2]
channel 1).
- The switched status is displayed by the green LED behind [KL.25]+[Kl.26].
- The function of the input is set via [M.b9].
- Simultaneous actuation of input A and input B has an emergency stop function.
[Kl.26]+[Kl.27] input B (partial opening/ active leaf / close)
- Input for pushbuttons, key-operated switch, external radio, etc.
- The controls must have a floating contact, which is open in the idle condition (make
contact).
- Several pushbuttons, etc. can be connected in parallel.
- The input is connected internally parallel to the slot of the radio receiver ([Bl.2]
channel 2).
- The switched status is displayed via the green LED behind [Kl.26]+[Kl.27].
- The function of the input is set via [M.b9].
