Single Phase Motor Energy Control - Page 15 of 20
Certain system compressors may stall in the event of a restart within the two-minute period
with EnviroStart fitted. These are generally, but not always, systems with a mechanical
thermostat fitted. If you experience problems with the unit re-starting in such conditions then
use the inbuilt timer feature of EnviroStart by switching DIP 6 into the “ON” position. This will
cause the unit to always wait two minutes before a restart is allowed ensuring backstop
pressures are equalized within the compressor circuit. (Default value is “OFF”).
4.4 PCB MOUNTED LED INDICATORS
LED 1
Energy Save Enabled
On to indicate that unit is running in energy save mode and is
within a pre-set band of energy savings around the level as is
set by DIP Switches 2, 3 and 4.
LED 2
Power On
Illuminates when unit is powered and ready to operate,
indicates that initialisation self test has been completed. When
flashing it indicates that the two minute “delay-start” timer,
(enabled through DIP Switch 6), is running. The flashing light
will stop as the motor starts after the two minute period.
LED 4
Current Limit
Illuminates when a fault condition is detected by the control
software. This light may flash periodically as the system
operates, indicating that a temnporary “stall mode” has been
detected. This is normal and is quite acceptable.
