Eliminating faults
−
See manual for the relevant
module
Eliminate short circuit/over
load (see manual for the spe
cific module)
Check and, if necessary, re
place the cable and connec
ted sensors/actuators.
Check connected actuators
as well as their connections
Eliminate undervoltage at
system supply or additional
supply (see Tab. 3/4 for pin
assignment)
Check signal area and para
meterised limit
Check signal area and para
meterised limit
Check valve and pneumatic
interface
Check valve and pneumatic
interface
Set or delete the limit value of
the condition counter by para
meterising
Check module (function/in
stallation), replace if neces
sary
