R14 = 15R ±1%
Measured value -
R17 + R19 = 94R ±1% (TP11 to CN5-2)
Measured value -
R16 + R18 = 94R ±1% (TP11 to CN5-3)
Measured value -
R29 = 1K ±1%
Measured value -
R31 = 1K ±1%
Measured value -
R32 = 1K ±1%
Measured value -
R33 = 1K ±1%
Measured value -
14.11 The heating element is controlled by
electronic double-pole disconnection.
In order to correctly test the insulation
resistance of the heater it is necessary
to temporarily fit the heater live
terminal (HL) wire to the Test terminal.
14.12 Replace control enclosure cover and perform earth continuity and electrical insulation tests.

14.13 Remove control enclosure cover and
move the heater wire back from the
Test terminal to the HL terminal.
14.14 Replace control enclosure cover.
14.15 Repeat electrical insulation tests.
