3. The factory setting should bring the moto r to full voltage in 15 to 3 0 seconds. If the sett ing is
not correct, adjust the ramp potentiometer counterclockwise for a shorter time, clockwise
for a longer time. (See F igu re 6 for starter compone nt placement.)
Check Oil Pressure and Compressor Stop
1. When the motor is up to ful l s pee d, note the differenti al oil pressure reading on the LID
default screen . It should be between 18 and 30 psid (124 to 206 kPad).
2. Press the Stop button and listen for any unusua l sounds from the compresso r as it coasts to
a stop.
Calibrate Motor Current Demand Setting
1. Make sure that the compressor motor rated load amps in the Service1 table has been
configured. Place an ammeter on the line that pass e s through the motor load current
transfer on t he motor side of the power fa ctor correction capacitors (if provided).
2. Start the compresso r and es t ablish a steady motor c ur r en t value between 70% and 100 %
RLA by manually overr idi ng the guide vane targe t val ue on the LID and setting the chilled
water set point to a low val ue. Do not exc eed 105% of the nameplate R LA.
3. When a steady motor current value in the desired range is met, compare the compressor
motor amps va lue on the Sta tus01 table to t he actual amp s shown on the ammeter on the
starter. Adjust the am ps v alu e on the LID to the actual valu e se en at the starter if there is a
difference. Highlight the amps value then press SELECT. Press INCREASE or DECREASE
to bring the value to tha t in dicated on the ammeter . Pr es s E NT ER when equal.
4. Make sure that the targ et guide vane position is rele ased into AUTOMATIC m ode .
