Diagnostic interface/visualization software (as of January 2006)
An interface with a 6-pole Modular socket (RJ-12) is provided for systemdiagnostics and process visualization.
This interface allows a data connection to be set up to the ROPEX visualization software using the ROPEX com-
munication interface CI-USB-1.
Only a ROPEX comunication interface is allowed to be connected to the diagnostic interface. Con-
necting another device (e.g. a telephone cable) could result in malfunctions or damage to the con-
troller.
The ROPEX visualization software is described in a separate document.

System monitoring/alarm output
To increase operating safety and to avoid faulty heatsealing, this controller incorporates special hardware and
software features that facilitate fault diagnosis. Both the external wiring and the internal system are monitored.
A system fault is reported or differentiated by means of the following indications:
A.)
Red "ALARM" LED on the controller with
three states:
1.
Blinks fast (4Hz):
The "AUTOCAL" function should be executed.
2.
Blinks slowly (1Hz):
The system configuration is incorrect and the zero calibration ("AUTOCAL" function) was unsuccessful .
3.
Lit continuously:
A fault is preventing the controller from being started.
Also in instances 1 and 2 if the "START" signal is activated simultaneously.
As a rule, it refers to an external wiring fault.
B.)
Alarm output signal on the controller
(terminals 14+9):
This logic output is:
•
LOW (OPEN)
in operating states A.1) and A.2), but high (closed) if a "START" signal is activated in one of these
states.
•
HIGH (CLOSED)
in operating state A.3)
An alarm can only be reset by applying a "RESET" signal or by switching the controller off and then
on again.
