SAFETY AND IMPORTANT WARNING ITEMS
2.
Protection by the hardware circuit
The output voltages from TH1 and TH2 (fixing
temperature sensor 2), TH3 (fixing temperature
sensor 3), and TH4 (fixing temperature sensor
4) are compared with the abnormality judgement
reference value in the comparator circuit. If the
output voltage from TH1, TH2, TH3, or TH4
exceeds the reference value, L2, L3, L4, and RL1
are turned off in hardware means.
Caution: Periodically check the TH2 and
TH4 faces contacting the roller,
and replace TH2 and/or TH4 if
any abnormality is detected.
Do not change the gap between
the roller and each sensor TH2
and TH4. When replacing TH2 or
TH4, check the specified
mounting dimensions.
The RL1 function must not be
deactivated under any circum-
stances.
3.
Protection by TS1 (thermostat (upper)) and
TS2 (thermostat (lower))
TS1 is turned off when the temperature of the
fixing roller (upper) exceeds the specified value,
and TS2 is turned off when the temperature of
the heating (upper) roller exceeds the specified
value, thus interrupting the power to L2 and L4
directly.
Caution: Do not use any other electrical
conductor in place of TS1 and
TS2.
4.
Protection by CBR2 (circuit breaker 2)
7075 only
The CBR2 interrupts the AC line for L3
instantaneously when an excessive current flows
due to a short in the AC line.
Caution: The CBR2 function must not be
deactivated under any circum-
stances.
