3.1 EDMxx Fault
On a dual-channel input, or a complementary input, one input went into the Run state but the
other input did not follow the change within 3 seconds.
On a dual-complementary input, one pair of inputs went into the Run state but the other pair of
inputs did not follow the change within 3 seconds.
•
Check the wiring
•
Check the input signal timing
•
Cycle input
On a dual-complementary input, with both inputs of one complementary pair in the Run state,
one input of this complementary pair changed to Stop then back to Run.:
•
Check the wiring
•
Check the input signals
•
Check the power supply providing input signals
•
Consider adjusting the debounce times
•
Cycle input
On a dual-complementary input, one input of a complementary pair went into the Run state, but
the other input of the same complementary pair did not follow the change within the time limit:
•
Check the wiring
•
Check the input signal timing
•
Cycle input
Internal failure— Contact BERNSTEIN AG (see
Input stuck high:
•
Check for shorts to other inputs or other voltage sources
•
Check the input device compatibility
•
Check for a short between inputs
•
Check for a short to ground
Input stuck low
•
Check for a short to ground
Missing test pulses:
•
Check for a short to other inputs or other voltage sources
•
Check for an open lead
Missing test pulses:
•
Check for a short to other inputs or other voltage sources
•
Check for an open lead
Missing test pulses:
•
Check for a short to ground
•
Check for an open lead
•
Check for an unstable signal on the input
A Two-Hand Control input was activated (turned On) while it was bypassed.
After the associated Safety Output turned Off, the AVM input did not close before its AVM
monitoring time expired:
•
The AVM may be disconnected. Check the wiring to the AVM
•
Either the AVM is disconnected, or its response to the Safety Output turning Off is
too slow
•
Check the wiring to the AVM
•
Check the timing setting; increase the setting if necessary
•
Contact BERNSTEIN
The AVM input was open, but should have been closed, when the associated Safety Output was
commanded On:
•
The AVM may be disconnected. Check the wiring to the AVM
EDM contact opened prior to turning On the Safety Outputs:
•
Check for a stuck On contactor or relay
•
Check for an open wire
