Error -
operating mode selection
Both inputs on which the operating mode selector switch is connected have the same signal
(both HIGH or both LOW).
■
■
■
■
Error - single-channel
opening detected
With a 2-channel sensor a 1-channel drop is detected. A restart is only possible if the sensor
is 2-channel open and then back to 2-channel closed
■
■
■
■
Error -
antivalent safety switch
With a 2-channel equivalent sensor (2 NC) nonequivalence is detected. (Instead of 2 identical
signals one signal is opposite, for example, channel A = HIGH and channel B = LOW)
OR with a 2-channel nonequivalence sensor (1 NC and 1 NO) an equivalence is detected.
(Instead of 2 different signals, both signals are the same)

■
Error - dual-channel control
when single-channel is selected
The inputs for sensors (e.g. I02 and I03) were set as 1-channel sensors (MSP Code,
3rd place = 2). On the deactivated odd input (here I03) a high signal is detected.
■
■
■
■
Error - control of a disabled
sensor
The inputs for sensors (e.g. I04 and I05) were not needed for the safety circuit and are set as
deactivated. At one or both inputs a HIGH signal is detected.
■
■
■
■
Error - feedback circuit (EDM)
The safety circuit is closed and the safe outputs are open: To restart the safety monitoring
the high signal is absent at the corresponding input, which means the feedback loop of the
integrated actuator is not closed.
■
■
■
■
Timeout -
Disturbed safety switch
The time lag between the signal changes of the two channels of a 2-channel sensor was
larger than the set monitoring time.
■
Error - Muting
A fault was detected in the muting sequence, which led to a halt (see fault case muting).
Eliminate problem, press Override and confirm with START / RESET.
■
■
■
Warning -
Interlock not locked
Setting the solenoid interlock parameters, for example, via the inputs I06 and I07:
The interlock (magnet) is driven, but the interlock does not lock.
■
■
■
■
Warning -
Safety circuit open
Part or all of the connected sensor is / are not yet closed.
■
■
■
■
Warning - Analogue Input:
Emergency-Stop active
After exceeding the limits AI0-3 and AI1-3, an Emergency-Stop function was activated and the
safe outputs were switched off.
■
■
■
■
Warning-
RESET necessary
The safety circuit is closed. To restart the safety monitoring the START / RESET is missing.
■
■
■
Warning -
Analogue input:
Interlock not released
When setting solenoid interlock parameters, for example, via the inputs I06 and I07 and
setting the limit parameters of AI0-0 and AI 1 0: After the limits AI0-0 and AI 1 0 are exceeded,
the solenoid interlock can be unlocked via the corresponding input. If an unlock request is trig-
ger via the corresponding input and the limit AI0-0 and AI1-0 are not reached, then a warning
message is triggered.
■
Manual operation is active
At the inputs where the operating mode selector switch is connected, the position "Manual"
has been detected, i.e. I00 = LOW and I01 = HIGH.
