• power control module (PCM - Figure 2.4 )
• main microprocessor module (MM)
• stepper valve module (SVM)
• standby and control boxes ( Figure 2.3 )
• control-box-mounted overload ground fault module (OGF, Figure 2.3 )
• control-box-mounted contactor control boards (CCB1 & CCB2, Figure 2.3 )
• display module (DM)
NOTICE
Under no circumstances should anyone attempt to repair sealed module internal components.
Should a problem develop with these components, contact your nearest Carrier Transicold
dealer for replacement.
a. Power Control Module
The power control module (PCM - see Figure 2.4 ) is responsible for distribution of power from the battery to the
system components, when starting, and then from the battery charger to the system components and to the battery
(for charging) once power is available.
The module houses the system relays, low voltage fuses and the DC current transformer (CT). The current
transformer provides a reading of the total 12 VDC system current draw (amps) to the main microprocessor at
terminal 2MM12 (see schematic diagram,
Section 10.3 ).
