1) Operation start and stop instruction
If SIG signal is short circuited (on), it will start to run. In case of opening (off),
operation will be stopped and expansion valve is closed immediately.
2) Utilization of auxiliary rely
Auxiliary relay can be used for alarm or compressor ON/OFF or liquid valve
ON/OFF In case of Pd= Off, use it as an alarm purpose.
If users enter pump down time (1~180 sec), it will be used for ON/OFF signal of
compressor.
3) Selection of electronic expansion valve
First of all, EVC10B needs to setup EEV mode to fit features of electronic
expansion valve. If EEV mode does not meet operation features of electronic
expansion valve, there can be malfunction. Please check it without fail. Operate
only number 2 and 3 of DIP SWITCH (DSW). After changing of setting, push
RES button on the right of product and restart. Users may input power
again.
