Power Entry and Control Module–Direct Current (PECM-DC)
The Power Entry and Control Module – Direct Current (PECM-DC) board
contains the electronics that distributes 24V DC power to the various
other components in the Maxum II Modular Oven configuration. Input
24V power is received from either the internal 24V Power supply or
optionally from an external source. The PECM-DC is mounted on the
back inside wall of the EC cabinet.
Overview
In addition to power distribution, the PECM performs the following
functions:
• Provides temperature control circuits for the oven heating
system, including temperature sense and over temperature
detection.
• Provides control circuitry for solenoid valves.
• Serves as a wiring distribution board for the I
2
C bus and for the
Solenoid Valves.
• Provides purge pressure detection circuitry (when the enclosure
is purged), or purge disable circuitry (when purge is not
configured).
