N O T I C E !
A thermocouple type must be set only when the temperature control
module is connected in conjunction with equipment which do not use a
PT100 as a temperature sensor.
If a thermocouple type is set, on warming up, an internal check is made whether a heating rate of +
3°C/minute is being reached. If this is not the case, a cable break in the temperature sensor or a
thermocouple not connected are assumed. The heating is turned off and the display shows "Thermal
Error: 2 (and/or 3) ". The error can only be corrected by removing the cause and switching on again.
17 ALARMS AND FAULTS
In the event of warnings, or errors, plain text information appears on the screen and simultaneously via
the LEDs on the controller front, as well as alarms via the group alarm connection (Art. No. 01G6170)
or alarms and warnings via the individual alarm connector (Art. No. 01G6175) (see 12.4.1. and
12.4.2).
In front of the plaintext information, is the serial number of the error message and the total number of
messages is specified, e.g. 1/3 ... = Error message 1 of 3.
Depending on the alarm and TCU configuration, an alarm can result in further alarms and warnings:
E.g. the liquid alarm (LA-Alarm:1,2) can trigger the pump alarm (Pump-Warn:1,2) and that in turn can
trigger the flow alarm (FA-Warn.:1,2).
The comm. error (e.g. interrupted connection cable RJ45) causes temperature sensor range exceeded
(T> max.:2,3) and flushing pressure alarm (flushing pressure not present!) as temperature sensors
and pressure sensors are connected to the communication module. From this follows the temperature
alarm (Hightemp.:2.3), then the pump alarm (Pump-Warn:1, 2) (with the appropriate TCU configuration
and then as a result the flow alarm FA-Warn.:1,2).
17.1 MEANING OF THE LEDS
Green LED: Coolant temperature within the setpoint range, there are no faults
Yellow LED: Flow alarm, low temperature of temperature controller modules and/or service time
reached or exceeded. Also message via individual alarm connection (see Section
12.4.2). In addition, device temperature <1° C or > 50° C, flushing pressure absent or
internal error requiring the device to be returned.
Red LED:
Temperature> 8 ° C or <2 ° C and/or humidity alarm and/or breakage of the cable of the
liquid sensor and/or high temperature alarm Temperature controller module at +10 ° C. to
Tset. Message also via group alarm connection (see Section 12.4.1), or via individual
alarm connection (see Section 12.4.2). In addition, short circuit and cable break of a
temperature sensor, and "Thermal Error" if during heating on channel 2 and/or 3, the
temperature does not increase
