Display and operation
As a standard, internal temperature (e.g. temperature of the bath for thermoregulation
units and outlet temperature for chillers) is displayed. By pressing the
SET-Key
a
switchover to the actual set point temperature takes place. Keep the
SET-Key
pressed
to change of the set point. Via the two arrow-keys you may select the set point. To
START / STOP
thermoregulation press the key
ON / OFF
. LEDs (Heating, Cooling and
Pump) give information on the actual operating status (e.g. Pump is working and
Cooling or Heating is on)
Advanced Functionality
Advanced Models contain, in comparison to standard models, of following possibilites:
1.
Possibility of sensor relocation via an external sensor connection (Pt100)
2.
An RS232 interface for controlling the machine.
Sensor relocation:
Keep the external Pt100 in a safe place!
A sensor relocation permits to control the temperature according to an external Pt100.
To activate this function, switch off the temperature control unit and connect the
external Pt100 to the designated Pt100 socket. Switch on the temperature control unit.
No switch over will take place (sensor relocation) when connecting the Pt100 if the
machine is operating. Please note, that within the internal and external sensor there is a
simple delta-T limit. This delta-T limit complies with the actual set point and the internal
sensor value. The internal sensor value lies always within a band of 5 K to the actual
set point.
RS232 interface:
Therefore, please see description on chapter 4.
