3.1.2 CONDENSATE DISCHARGE PARAMETERS PROGRAMMING
Push the SET key for 10 seconds to enter the parameters configuration menu: the display will show in
sequence the set point value, the code of the first modifiable parameter (C8) and its value).
Only if strictly necessary, use the UP and/or DOWN keys to change the displayed parameter value.
Press the SET key to store the previously changed parameter value or to browse the parameters
without changing them.
15 seconds after the last performed operation, the controller will return automatically to the normal
operation mode.
PARAMETER DESCRIPTION
Delay between condensate
C8
discharges
Time required for condensate
C9
discharge
NOTE: Changes entered for timing values will be effective only after exiting the programming, while changes to other
variables will be immediately effective.
Please remember that eventual changes to the configuration parameters of the machine could negatively affect its
efficiency. Thus, changes have to be performed by a person familiar with the operation of the dryer.
WARNING FOR USER:
IT'S FORBIDDEN TO ATTEMPT TO MODIFY THE OTHER CONFIGURATION PARAMETERS OF THE ELECTRONIC
CONTROLLER WITHOUT AUTHORIZATION AND COLLABORATION OF INGERSOLL RAND'S AUTHORIZED DISTRIBUTOR.
3.1.3 DISPLAY INDICATIONS
The controller is capable of recognizing certain types of anomalies in the drying circuit. In such cases, a message will blink on the
display, alternated to the current dew point value.

3.2 BEFORE START UP

Before starting the machine, make sure that all operating parameters correspond to the nominal data.
The dryer is supplied already tested and preset for normal operation, and it doesn't require any calibration.
Nevertheless, it's necessary to check the operating performances during the first working hours.

3.3 START UP

The operations specified below must be performed after the first start up and at each start up after a
prolonged inactive period of time due to maintenance operations, or any other reason.
1. Make sure that all instructions contained in chapters INSTALLATION SITE and INSTALLATION
have been observed.
2. Ensure dryer by-pass is open and air inlet/outlet valves closed. (if existing).
3. Wait 5 to 10 minutes until machine has achieved its standard operating parameters.
4. Slowly open the air outlet valve and successively open the air inlet valve.
5. If existent, close the air by-pass valve.
6. Check if the condensate drain is working properly.
7. Check if all connecting pipes are properly tightened and fixed.
Before disconnecting the dryer from electrical power supply, use ON/OFF switch to stop the
dryer. Otherwise wait 10 minutes before switching the dryer on again, in order to allow freon
pressure to rebalance.
4. MAINTENANCE, TROUBLESHOOTING AND DECOMMISSIONING

4.1 MAINTENANCE

Before attempting any maintenance operation, make sure that:
1. No parts of the system are under pressure.
2. No parts of the system are electrically powered.
WEEKLY OR EVERY 40 HOURS OF OPERATION
Verify the temperature on the control panel display is acceptable.
Visually check if the condensate is drained regularly.
MONTHLY OR EVERY 200 HOURS OF OPERATION
Clean the condenser with compressed air, taking care not to damage the condenser fins..
At the end of the above mentioned operations, check if the dryer is working properly.
Check the condition of any filters installed with the dryer. Replace elements as needed.
YEARLY OR EVERY 2000 HOURS OF OPERATION
Check if the flexible tube used for condensate drainage is damaged and replace it if necessary.
Check if all connecting pipes are properly tightened and fixed.
At the end of the above mentioned operations, check if the dryer is working properly.

4.2 TROUBLESHOOTING

NOTE: FOLLOWING BEHAVIORS ARE NORMAL CHARACTERISTIC OF OPERATION AND NOT TROUBLES
•
Display of message ESA and ES2 in case of operation without load or low load.
•
A 90 seconds delay for dryer to start after closing remote ON/OFF contact (see electrical wiring diagram).
