SCS 104
5 Operation and control
NOTICE
The device must not be operated beyond its specifications.
After switching on the system the block temperature will be displayed. The display will flash until the block temperature has
reached the set target value (± adjustable alarm range). The status contact is in the temperature 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 appears, please refer to item " Troubleshooting [> page 19]”.
Please refer to the technical data for performance data and maximum ratings.
5.1 Start up
Confirm the SCS is correctly mounted and wired and perform the following procedure in order:
Verify the filter (5) cover is correctly closed (tighten clockwise by hand).
Switch on the SCS. The on/off switch (20a) is located on the PS0191 (20c) front panel.
– The cooler fan will turn on.
– The green power LED will illuminate.
– System mode LED (green) “Sample” will light.
– The cooler display (30) shows the system software version for some seconds (e.g. “d2,03”, “n1.13”)
– On initial power up the cooler display (30) will register approximately ambient temperature (blinking), and the temperature
alarm LED will be red.
The alarm LED will continue to stay red until the cooler temperature drops to 8 °C (46 °F). When the cooler temperature drops to
8 °C (46°F), the sample pump will come on.
The condensate pump comes on any way.
The SCS is now ready for operation.
