Troubleshooting
Error message Cause Correction
Photocells dark: 10; 11; 12;
13; 14; 15; 16; 17 Photocell does not respond to change of
light Adjust photocell correctly; reflective film
dull, clean if required; replace photocell
ES 02 Switch not pressed
No air pressure: adjust switch; replace
switch
I/O Communication Error
Error in data transmission between
controller and I/O module
Check all cable connections (flat ribbon
cable) to 9020013 /. 9020024; if
required, replace controller module
9020013 or module 9020024
Cross transport position
read error No valid cross transport position
readable from controller
If this message appears only
intermittently (alternating with other error
messages), data transmission via bus is
faulty:
Check flat ribbon cable connector of
adapter module 9020020 > 9020013; if
required, replace adapter module
9020020; if required, replace I/O module
9020013.
Cross transport position
The cross transport did not reach the
target position
Check CT motor with test program
„Cross transport motor continuous test“;
check connections to cross transport;
Check 110 V DC supply for stepper
motor; replace BERGER power unit;
replace BERGER motor; replace
adapter PCB 9020020; if motor fails to
run, the cause may be the cross
transport driver circuit or power unit:
Check the state of the LEDs at the
power PCB (BERGER) and continue
troubleshooting in accordance with
diagnostics for BERGER motor, as
required; check connection to cross
transport (connector); check connection
between 9020020 and power unit
(connector); replace adapter PCB
9020020.
Cross transport stop
Limit switch ES01 has switched during
transport although internal distance
counter detected that cross transport
was far from this switch
– Check distance counter with test
program (steps); if counter is faulty,
replace motor or adapter PCB 9020020;
if counter is OK, check switch ES01
and connections.
