4.5.1.2 24 V DC
The voltage supply for the sample gas cooler must be connec-
ted to terminals 8 and 9 on the power board. The earth con-
ductor must be connected to the earth bolt on the housing.
The operating voltage of the pumps which may optionally be
connected is 24 V DC. Please note the polarity when connect-
ing.

5 Operation and control
NOTICE
The device must not be operated beyond its specifications.
After starting the cooler, the software version will be dis-
played, followed by the block temperature. The display S2 will
stay on until the block temperature has reached the preset
value (± adjustable alarm range). The status contact is in the
Alarm position.
Once the target temperature range has been reached, the
temperature will continuously be displayed and the status
contact switches over.
If the display flashes during operation or an error message ap-
pears, please refer to item "Troubleshooting".
Please refer to the data sheet for performance data and max-
imum ratings.
When starting for the first time, optional equipment pur-
chased separately must be registered once. The options heat
exchanger material, analog output and moisture detector
must be configured, tested and registered in the menu.
