Password required.
7.7.3.1 Calibration (offset)
If any deviation occurs in the pressure and temperature
displayed between the controller and the master gauge,
ask ELGi service engineer to offset the valve. Factory fitted
sensor/controller are pre-calibrated.
7.7.3.2 Programmable relay
Select the programmable relay 1 or 2 using the ∆ and ∇
keys. Then press Enter to assign any one of the following
functionalities for the relay.
Default
7.7.3.3 Temperature
1. Fan temperature * - (If a fan is equipped with
machine) This option causes the fan relay to energize if
the discharge temperature reaches the set value. It will
de-energize when the temperature decreases to -15ºC
from the set value.
2. Inhibit temperature - This option causes the
compressor to start when the discharge temperature is
higher than the set value (if Temperature inhibit is
enabled in factory settings).
3. Temperature Inhibit time - - This option causes the
compressor to wait for this specified time to reach the
Inhibit temperature. If not, it trips because temperature
is not building.
7.7.3.4 Auto drain valve**
The auto drain valve is a special feature that helps prevent
water from entering into compressed air delivery. This
function enables the drain valve to switch on and off based
on a specified time in the menu. The default setting is 5
sec ON with a 4 min interval. It is programmed in the relay
menu available in service.
7.7.3.5 Maintenance
The system will warn when it reaches 0000 hours for you
to change the filter. The time limit will vary depending on
the model. Contact your authorized dealer to learn more.
Good practice is to record the details in the operator/
maintenance menu once the filter is replaced.
7.7.3.6 Self test
Perform a self test to verify the controller display, mimic
LEDs, keys, analog and digital inputs/outputs. Follow the
instructions that appear in the screen.
7.7.3.7 Unload mode
If you enable this option, the compressor will run only in
the unload mode. The option disables compressor load
mode. (This mode is used for service and maintenance
purpose).

Conduct self test only after you totally disconnect compres-
sor wiring from the controller. Else, the compressor will
sustain severe damage. A self–test must be done only by
an authorized service person.
