Errors - possible causes
What to do
1
self-acting start with different switch-off delay
switch off supply voltage, adjust same switch-off delay, switch
on supply voltage -> device will be start again
start over start-button with different switch-off delay
switch off supply voltage, adjust same switch delay, switch on
supply voltage -> device could start again
changing of adjusted time before or during the start
switch off supply voltage, adjust favored time, switch on sup-
ply voltage --> device could start again (by start with start-
button) or device starts automatically (by self-acting start)
disparity of both channels resp. only one channel notice the
error, simultaneity of the microcontroller is wrong, no ac-
knowledgment of one microcontroller
look at the error message of the other channel
2
input circuit is wrong
check wiring of input circuit
at two-channel operation: error state at start if both channels
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
close or open the safety-gate complete, check the wiring
which is connected to the releasing element, check the emer-
gency-button (defect)
3
internal instantaneous relay is damaged
maybe the max. mechanical lifetime of the relay is reached -->
replace the relay
4
internal time-delay relay is damaged
maybe the max. mechanical lifetime of the relay is reached -->
replace the relay
5
signal of pin S11 resp. pin S22 has a wrong value
check wiring of input circuit
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
connected to any clamp
check wiring of input circuit
at one-channel application: short-circuit of pin S11 resp. pin
S10 with 24V supply voltage or with another positive voltage
connecetd to any clamp
check wiring of input circuit
by self-acting start and still activated releasing element: if the
feedback loop is closed not until after standby-time
check wiring to the external contactor/contactors, check the
function of the external contactors
by self-acting start and activated releasing element: if the
feedback loop is closed not until after approx. 0.5s after the
relay SAFE-T is connected to the supply voltage
check wiring to the external contactor/contactors, check the
function of the external contactors
by self-acting start and activated releasing element: if the
bridge for self-acting start will be opened, i.g cable break
check wiring to the external contactor/contactors, check the
function of the external contactors
6
changing of adjusted time during the switch-off delay or
standby-time
switch off supply voltage, adjust favored time, switch on sup-
ply voltage --> device could start again (by start with start-
button) or device starts automatically (by self-acting start)
internal interrupt error (ROM test failed, synchronization error)
replace device, if necessary send it in because of garanty or
repair, or look at the error message of the other channel
7
at two-channel operation:only one channel was switched off,
one emergency-button does not open or is clotted
check the wiring to the releasing element, check the function
of the releasing element
there is a defect/bad contact on the push-button or connector
(maybe because of a cable which is not correctly screwed on)
resp. push-button bounces longer as 1s
check the wiring to the releasing element, check the function
of the releasing element
overstep of simultaneity of both channels
check the position of safe-gate button, both buttons have to
pushed or unhanded within 1s, check the wiring to the releas-
ing element
at two-channel operation: unlocking of the emergency-button,
unclose the safety-gate before the fall time runs off (device is
not retriggerable)
reset the device (short switch off the supply voltage), after
that, the device could start again (by start with start-button) or
device starts automatically (by self-acting start)
SAFE-T was started with two different times (times were
adjusted in a condition without supply voltage)
switch off supply voltage, adjust favored time at both buttons
and at the DIP-switch (must be the same value), switch on
supply voltage --> device could start again (by start with start-
button) or device starts automatically (self-acting start)
at one-channel operation: bridge S21, S22 will be opened
while the device is in an active condition (relay is activated)
check the wiring to S21 and S22
8
changing of the adjusted time during operation (relay is acti-
vated, releasing element is not activated)
switch off supply voltage, adjust favored time, switch on sup-
ply voltage --> device could start again (by start with start-
button) or device starts automatically (by self-acting start)
