Er.OP
Self tuning error
Extinguish error signal by pressing the „E“-key.
Check the self tuning conditions and restart.
Er.SY
System error
Extinguish error signal by pressing the „E“-key.
Check all parameters.
If the error signal continues please send the controller
for examination.
Co.A1
Alarmconfiguration of alarm A1: OFF
No alarm signal available

Er.Cu
Short circuit current in one or more loads.
Check load.
Look at ssr`s with short circuit.
The zone or the zones were a permanent current is measured, can be detected by controlling the actual
temperatur indications of all zones. The tempearture should be too high.
XVIII. Installation Instructions
Make certain that the devices described here are used only for the intended purpose.
They are intended for installation in control panels.
The controller must be installed so that it is protected against impermissible humidity and severe contamination.
In addition, make sure that the permitted ambient temperature is not exceeded.
The electrical connections must be made according to the relevant locally applicable regulations.
If using a thermocouple sensor, the compensation cables must be laid directly to the controller terminals.
Transducers must be connected only in compliance with the programmed range.
Transducer cables and signal lines (e.g. logic or linear voltage outputs) must be laid physically
separated from control lines and mains voltage supply cables (power cables) and must be shielded.
Spatial separation between controller and inductive loads is recommneded.
Interference from contactor coils must be suppressed by connecting adapted RC-combinations parallel to the coils.
Control circuits (e.g. for contactors) should not be connected to the mains power supply terminals of the controller.
