Temperature Detection Error
After adjustment of the glue temperature,
the glue temperature thermistor (S56)
detected a temperature lower than 135C
for more than 10 sec.
• Heater (HTR1) defective
• Glue thermistor (S56)
defective
SC797-21 B
The glue level thermistor detected a
temperature higher than 170C for longer
than 10 sec. after the glue had warmed
up.
-or-
The glue level thermistor detected a
temperature higher than 100C for longer
than 10 sec. after the glue had warmed
up.
• Glue level thermistor (S58)
defective
Protection Circuit Error
SC797-22 B
The thermostat (THSW1) inside the
gluing unit detected an abnormally high
temperature.
• Glue heater (HTR1)defective
• Thermostat (THSW1)
defective
Glue Surface Error 1
The surface of the glue in the vat did not
reach the lower limit position. This error
occurred when the glue surface was
detected below the lower limit position 4
times in succession during the glue
replenishment cycle.
• Glue has clogged in the vat
• Glue supply defective
• Glue level thermistor (S58)
defective
SC797-23 B
The glue level thermistor could not
detect the glue surface at the upper limit
position: 1) After glue was detected
above the low limit mark, and 2) After 12
glue packets were supplied, and 3) No
glue had been recently applied.
• Glue has clogged in the vat
• Glue level thermistor (S58)
defective
Glue Surface Error 2
SC797-24 B
Without a glue vat refill, the glue level
thermistor could not detect the level
of the glue below the upper limit (full)
level, even after the application of
25.42 g of glue.
• Glue application abnormal (not
applying correctly)
• Glue level thermistor (S58)
defective
Glue Level Thermistor (S58) Adjustment Error
One of the following errors occurred in the adjustment data for the glue
level thermistor:
1. Glue level thermistor 1 value (low limit) was out of the range:
128C±14C)
2. Glue level thermistor 2 value (high limit) was out of the range:
142C±10C)
3. Glue level thermistor adjustment value 1 was larger than for
adjustment 1.
