5.2.3 Radiant Heater
The 115 volt radiant heater is rated at 225 watts at 104 volts. It is powered by isolated 115 volts from the
heater isolation transformer switched by the radiant warmer SSR.
The resistance of the radiant heater is about 24 ohms.
To measure the radiant heater resistance on devices, disconnect the brown wire on the radiant heater SSR
and the connector from J54 on the relay board. Measure between harness connector pin 3, and the brown
wire.
The radiant heater resistance can also be measured by removing the heater housing and measuring on the
radiant heater harness.
5.2.4 Power Supplies
The 5V and 12V supplies are generated on the power supply.
+5STBY is generated on the relay board. These voltages are distributed to the control board, SBC, servo
oxygen board, and expansion slots through a harness with a series of 4 pin connectors. The easiest place to
measure the power supplies is at one of the spare 4 pin connectors on this power bus.
The 5VSTBY should also be present during power fail.
+5VAN and -5VAN are generated on the control board and are only used on the control board. They can be
measured on the test points on the control board.
Caution:
To avoid damaging a harness, make sure you do not pull the harness by the cable
wires. Instead, use the connector body to disengage or to engage the connectors.
