12.4 Error code
The red Diag.-LED serves as a status indicator. During regular, fault free operation the LED is only lit,
when a radio remote signal is received. An error code is given, when the controller detects a fault. the
Diag.-LED flashes max. 12 times, then a break, then repeats the flashing code.
error code Cause/solution
2 x flashing
Limit switch “OPEN” did not open after the learnt running time. The limit switch has a
short circuit.
3 x flashing
Limit switch “CLOSE” did not open after the learnt running time. The limit switch has a
short circuit.
4 x flashing
Both limit switches signal at the same time. While SEA and SEZ signal at the same
time, the controller is blocked.
5 x flashing
The power supply limit for the external equipment 12V and/or 24V has been reached.
The power source load is too high. The controller is blocked. Check the connected
equipment.
6 x flashing
Photo-cell error. The following error occurred during the photo-cell test. The transmitter
is inactive but the receiver does not signal an obstacle.
7 x flashing
An error occurred during learning of the torque power for the reversing on obstacle.
Either the controller, the motor, or the capacitor of the motor are faulty.Check the
above and repeat the learning of the running time. If the error still exists the controller is
faulty.
8 x flashing
The EEPROM has lost the data. Repeat the learning of the running time. If the error
still exists the controller is faulty.
9 x flashing The EEPROM is faulty.
10 x flashing
The controller has detected a fault in the redundant detection of the “stop” contact. The
controller is faulty.
11 x flashing One of the motor relays has not switched off. The controller is faulty.
12 x flashing The controller detects that the “Triac” has not switched off. The controller is faulty.

Attention:
You may use the service device ZS701 to read the error memory of the controller.
