9. Error Displays
Display Cause Possible remedy
SP.Lo Lower setpoint limit has been reached Reduce limit, if need be
SP.Hi Upper setpoint limit has been reached Increase limit, if need be
LOC Parameter has been locked Unlock, if need be
Hand Instrument operates in manual mode Check sensor and cable
Automatically switch over because of
a sensor error (if this is programmed).
Er.Hi Top range end has been exceeded, Check sensor and cable
sensor defect
Er.Lo Bottom range end has been exceeded, Check sensor and cable
sensor defect
Er.OP Selftuning error Extinguish error signal by pressing
the „E“-key. Check the self tuning
conditions and restart.
Co.A3 Alarm configuration alarm A3 = OFF No alarm monitoring possible
Co.A2 Alarm configuration alarm A2 = OFF No alarm monitoring possible
Er.SY System error Extinguish error signal by pressing
the „E“-key. Check all parameters.
If the error signal continues please
send the controller back for
examination.
10. 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 have to be made by well trained personnel according to the relevant
locally applicable regulations only.
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).
To keep the CE-conformity it is nessesary, to use for sensor- and low voltage signal lines shielded cabels.
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.
IMPORTANT:
Before operation, the unit must be configurated for its intended purpose (e.g. controller type, sensor type
and range, alarm adjustment etc.).
Please see „Configuration Level“.
