Version 1
The integrated clock can only be set and read out using ROPEX visualisation software.
A maintenance-free condenser is used for operation of the clock. There is no installed battery that has to be
changed.
The controller must be switched on for at least 3 hours to charge the clock condenser completely. When the con-
denser is switched off, a fully charged condenser can operate the clock for approx. 2…4 weeks. If the controller
is switched off longer, the date and time must be set again. This must be done with the ROPEX visualisation soft-
ware (
section 8.11 "USB interface for visualisation software ROPEXvisual
The condenser is discharged when shipped from the factory. During initial start-up of the controller, the clock must
be set when the error messages in the data storage are to be stored with date and time.
Operation of the controller is possible without the clock being set. Then only invalid values for the date and time
are stored in the data storage. The behaviour of the temperature controller is not influenced by this.
8.15
System monitoring/alarm output
To increase operational safety and avoid incorrect welding, this controller has hardware and software measures
for error diagnosis and output of differentiated error messages. Both the outer wiring and the internal system are
monitored thereby.
This characteristic helps the operator considerably in localising a defective operating status.
A system malfunction is reported or differentiated through the following elements:
A.)
Red LED “ALARM” at the controller with three statuses:
1.
Flashes quickly (4 Hz):
Means that the AUTOCAL function should be performed (error no. 104…106, 211, 302, 303).
2.
Flashes slowly (1 Hz):
Means that the system configuration is incorrect and therefore the executed zeroing (AUTOCAL function) was
not successful (
section 7.2 "Device configuration" on page 14). This corresponds to the error numbers
111…114.
3.
Lights up continuously:
Displays that malfunctions are present that prevent a start-up (error no. 101…103, 107, 108, 201…203, 307,
308, 9xx).
In cases 1 and 2, when the START signal is also activated.
These are usually external wiring errors.
B.)
Alarm output signal at the controller (terminal 18):
This is logic output in the factory setting:
•
LOW (OPEN)
in the operating statuses A.1) and A.2), but becomes HIGH (closed) when a START signal is
issued in this status.
•
HIGH (CLOSED)
in case A.3)
If the alarm output is configured differently than in the factory setting(
tion of the alarm output" on page 15), these statuses are inverted.
C.)
Output of the error number via actual value output 0…10 VDC (terminal 17+13):
As a temperature display is not required in case of malfunction, the actual value output is used to output the error
in case of alarm.
Offered for this purpose, within the 0…10 VDC range, are 13 voltage levels, each of which has one error number
assigned. (
section 8.16 "Error messages" on page 29).
For statuses that require AUTOCAL – or when the device configuration is not correct – (error no. 104…106,
111…114, 211, 302, 303), the actual value output switches back and forth between the voltage value that corre-
sponds to the error and the end value (10 VDC, i.e 300 °C or 500 °C) with 1 Hz. If the START signal is output
during these statuses, the voltage value no longer changes.
