3.5. Resetting maintenance timers
Note! When a maintenance pre-alarm message is manually reset, it will no longer appear as long as the
compressor is ON. The pre-alarm is displayed again when the compressor is powered again.
Maintenance timers can only be reset when the compressor is OFF. When the compressor is OFF, the display
shows an “OFF” or “---” message, depending on the conditions described in subsection "Display" on page 5.
1. To view the first maintenance code (S01), press and hold Reset button for about 3 seconds.
2. To reset the first maintenance code, press and hold the Reset button for about 3 seconds. The value is
replaced by the default value and the second maintenance code will be displayed.
3. If you do not wish to reset the first hour meter, but want to switch immediately to the second one instead,
press and release the Reset button. The second maintenance code appears on the display, and its timer
value will be visible after 1 second. To reset the value, press and hold the Reset button for about 3
seconds.
4. Scroll through all maintenance timers as described above, resetting their values if necessary, until the
“OFF” or “---” message is displayed again.
3.6. Viewing operating timers
Operating timers count the total operating time and total load operating time of the compressor. The
operating timers are available for viewing when the compressor is ON.
1. To view the “h-t” message, total hours, press and hold the reset button for 3 seconds. Total time will appear
straight after.
2. To view the “h-L” message, load hours, press and release the Reset button again. Load operation will
appear straight after.
Note! The counting of load operating hours is relative to the closing time of the relay supplying the
load/unload solenoid valve; the counting of total operating time is relative to the closing time of the line
contactor (that is, the time interval during which the motor is running).
Note! Operating time is stored to the memory every 15 minutes; if a power failure occurs during
compressor operation, the entire 15 minute fraction will be lost.
