6.2. MODIFYING HOUR COUNTERS
The unit holds 3 different run hour counters:
MESSAGE DESCRIPTION
C-H
C-HC-H
C-H
Total compressor hours (ON_LOAD+OFF_LOAD+STOP)
This counter increments while the RUN led is on.
R-H
R-HR-H
R-H
Total motor run hours
(ON_LOAD+OFF_LOAD)
This counter increments while the motor runs.
L-H
L-HL-H
L-H
Total load time (load contactor active)
This counter increments while LOAD led is on.
Hour counters can only be modified while the compresor
is in STOP mode.
In order to modify hour counters:
- Hold pressed together MENU , RUN and STOP buttons for 3 seconds. If
the high level password is not entered in the last 90 minutes, the unit will ask password
(US R
USRUSR
USR).
- Enter password.
- The upper display will show C-H
C-HC-H
C-H message.
- Adjust required hour counter value with RUN and STOP buttons.
- Press MENU button for 3 seconds, the display wil show SEt message and the
counter will be adjusted to the new value. If MENU button is pressed for short
duration, then the value will not be modified and the next hour counter will be displayed.
Same steps are repeated for further modification.
After modifications, the display will return to pressure-
temperature display mode.
