Follow these instructions to connect the status alarm and power cables:
• release the screws (7 pcs.) from the cooler hood and remove the hood;
• put the cables (6-12 mm) through one of the cable glands in the bottom plate, and connect them
according to the electrical connections in Fig. 5;
17 Start-up
The controlled cooling system of the ECMExII permits automatic start-up of the cooler.
The following description applies to a start-up at an ambient temperature of > 8 °C [> 46.4 °F] only.
Only carry out any work at the gas cooler, when the process and the
environment of the cooler is declared as an explosion-free zone. A zone is
declared as explosion-free zone, if it is free of explosive atmosphere.
Only open the protective cover in front of the temperature controller, when
the process and the environment of the cooler is declared as an explosion-
free zone. A zone is declared as explosion-free zone, if it is free of explosive
atmosphere.
Warning
Connect the cooler to earth (electrical bonding terminal).
The bleeder resistor needs to have an overall value of < 10
6
Ω .
Note
Before starting up the gas cooler, it must be placed in its operating position
for at least two hours. The liquid inside the system may have been
redistributed, and this could cause problems during operating.
The following steps should be carried out before initial start-up:
•
Connect the cooler unit to the mains power supply; Make sure that the equipment is connected
to the correct mains voltage, 115 V or 230 V, as shown on the type plate.
• Connect the status contact output to the measuring station;
Note
Connect the status contact output to an external sample gas pump or a solenoid
valve in the gas line. In case of an alarm incident, this can protect the whole
analysing system by immediate interruption of the gas supply.
