Errors - possible causes
code
disparity of both channels resp. only one channel notice the
1 error, simultaneity of the microcontroller is wrong, no
acknowledgment of one microcontroller
input circuit is wrong
at two-channel operation: error state at start if both channels
2
have different states (e.g. opened or closed), i.e. if safety gate
is not complete open resp. closed / or emergency-button has
a faulty channel or if there is a cable break which is connected
to the emergency-button resp. safety-gate watcher
3 internal instantaneous relay is damaged
4 internal time-delay relay is damaged
signal of pin S11 resp. pin S22 has a wrong value
transverse conclusion of pin S11 with pin S21, or short-circuit
of pin S11 resp. pin S21 with 24V supply voltage or short-
circuit of pin S11 resp. pin S21 with another positive voltage
5
connected to any clamp
at one-channel application: short-circuit of pin S11 resp. pin
S10 with 24V supply voltage or with another positive voltage
connected to any clamp
6 internal interrupt error (ROM test failed, synchronization error)
at one-channel application: an interruption of channel 2 (S21-
S22) was proceed while active condition of device
7
at one-channel operation: bridge S21, S22 will be opened
while the device is in an active condition (relay is activated)
disparity of both channels resp. only one channel notice the
error, simultaneity of the microcontroller is wrong, no
acknowledgment of one microcontroller
8
Initial operation of device with two different time settings
(difference > 0.5s) or, changing of the adjusted time during
operation (relay is activated, releasing element is not
activated)
Flashing diodes K3(t) and K4(t):
The safety device SAFE T ON supports the infinitely simultaneity. At two-channel
applications, if switching off will proceed with one channel only, or if the initial switch has a
malfunction (glued contacts, opening operation doesn't works accurate), the diodes K3(t)
and K4(t) will flash. The diodes flashes so long (waiting status) to the second channel is
also opened.

Elimination of errors
look at the error message of the other channel
check wiring of input circuit
close or open the safety-gate complete, check the wiring
which is connected to the releasing element, check the
emergency-button (defect)
maybe the max. mechanical lifetime of the relay is
reached replace the relay
maybe the max. mechanical lifetime of the relay is
reached replace the relay
check wiring of input circuit
check wiring of input circuit
check wiring of input circuit
replace device, if necessary send it in because of warranty
or repair, or look at the error message of the other channel
operating error, switch off the power supply, switch on the
power supply device can be restarted (with manual start),
or device will start automatically (auto run configuration
check the wiring to S21 and S22
look at the error message of the other channel
switch off supply voltage, adjust favored time, switch on
supply voltage device could start again (by start with
start-button) or device starts automatically (by self-acting
start)
