instructions.
ArmorStart Safety Bulletin 280/281/284 Distributed Motor
Controllers Safety Circuit Troubleshooting
➀ Non-safety stop – The 1732DS-IB8XOBV4 does not remove 24V DC from P and M of A1/A2 when
a non-safety stop is executed. Restarting the controller after a non-safety stop is not inhibited by
the safety circuit.
➁ Safety stop – The 1732DS-IB8XOBV4 removes 24V DC from P and M of A1/A2 when a safety stop
is executed. This opens both contactors. Restarting the controller stop is inhibited if the SM feedback
is open. The program in the safety controller does not permit the 1732DS-IB8XOBV4 to apply 24V DC
to P and M in the A1/A2 cable.

not start
Off Off Off 1. The disconnect switch of the ArmorStart
controller is open.
2. 24 VDC not supplied to A1 and A2 at
A1/A2 connector because cable or
connections are defective.
3. 1732DS-IB8XOBV4 not supplying 24 VDC
to A1 and A2 pins of A1/A2 cable.
1. Check disconnect switch.
2. Verify cable and connections.
3. Refer to IN PWR/OUT PWR Indicators in
1732DS-IB8XOBV4 manual.
Off Flashing Off There is an ArmorStart controller fault. Refer to ArmorStart Manual for controller fault.
On Off Off After non-safety stop ➀
1. The controller is not receiving a RUN
command.
After safety stop ➁
1. The controller is not receiving a RUN
command.
2. SM cable connections (SM1, SM2) open.
3. SM feedback is open inside control
module.
4. 1732DS-IB8XOBV4 is reporting open SM
feedback from the IN0...INn inputs.
After non-safety stop ➀
1. Check RUN command source.
After safety stop ➁
1. Check RUN command source.
2. Check SM cable and connections.
3. Check SM feedback inside control
module.
4. Refer to I/O Indicators in
1732DS-IB8XOBV4 manual.
On Flashing Off ArmorStart controller fault is inhibiting
ArmorStart controller start function. Refer to ArmorStart Manual for controller fault.
On Off On 1. Three-phase power is not being supplied
to controller (Bulletin 280/281
controllers).
2. 24 VDC not supplied to P and M at A1/A2
connector because cable or connections
are defective.
3. 1732DS-IB8XOBV4 OUT0...OUTn outputs
are not supplying 24 VDC to pins P and M
of A1/A2 cable assembly.
1. Verify 3-phase voltage at ArmorStart
controller input.
2. Verify cable and connections.
3. Refer to I/O Indicators in
1732DS-IB8XOBV4 manual.
