1814 START-UPThe control electronics of the EC30(/FD) permit automatic start up of the cooler, which also ensuressafe and guaranteed operation regardless of external influences such as a power failure. The errordiagnostics guarantee full monitoring and reporting of possible sources of error. The followingdescription is valid for startup of the gas cooler for an ambient temperature > 5 C.NOTE!Before starting up the gas cooler, it must be placed in its operating positionfor at least two hours. The liquid inside the system may has beenredistributed, and this could cause problems in operating!The following steps should be carried out before initial start up:Connect the cooler unit to the mains power supply; Check that the equipment is connected tothe correct mains voltage, 115V or 230V, as shown on the type plate.Lead the status contacts for reporting of low- and excess temperature to the measuring station.NOTE!The status contacts must be connected to the external sample gas pump orto a valve in the sample gas line to protect the entire analysis system byimmediately cutting off the gas supply in the event of error messages fromthe cooler!14.1 FUNCTION SEQUENCE AND LED FUNCTION DISPLAYThree function display LEDs are provided to give a visualization of the function sequence during startup of the cooler. According to the type of installation, they are located either on the front panel or theback panel of the cooler (fig. 2). The top LED (red) indicates that the temperature set by the ECautomatic control electronics for the pre-cooler stage has been exceeded or has not been reached.The two-colour (pink/green) LED in the middle shows that the cooler compressor is operating (on/off).The bottom red function display LED gives an alarm if the pre-cooler stage temperature falls too low orif the low-temperature stage temperature is exceeded.Switching the cooler onAs soon as there is a mains voltage, the top red LED lights up. Thisindicates that the temperature of the pre-cooler is min. 3 C above the settemperature of +1 C. The two-coloured LED in the middle lights up as pinkonce the cooler compressor is in operation.°C >ONredpinkgreen°C
19Switching on the low-temperature stagesAfter approx. 30 minutes the pre-cooler stage has been cooled down to atemperature below +4 C. The top red LED goes out and the bottom red LEDlights up. The low-temperature stage is activated and starts operating atfull power. The cooler compressor is switched of as soon as the pre-coolerstage reaches the controlled temperature of +1 C. The middle LED lights upgreen. The cooler compressor will be alternately switched on and off by theEC automatic control electronics in a load-dependent cycle. The middle LEDwill alternately light up pink and green (normal operating functions).°C >ONpinkgreen°C ONpinkgreen°C
