•
Detects the burnout of any one of a group of heaters.
•
Detects the burnout of 3-phase heaters.
•
Detects SSR short-circuit failures.
•
Error detection level can be easily set with a switch.
•
Mounts to a DIN track or with screws.
•
Three types of input terminals available: M3 terminals,
screwless clamp terminals (detachable), or compact slotted
screw terminals (detachable).
•
Certified for CSA and EN (TÜV).
•
The G3PF-2@@B-@@@ Series is UL certified.

Operation
■
Error Detection Function
●
Setting the Heater Burnout Detection Level
•
The heater burnout detection level is set with switches on the front of the G3PF.
•
Turn the switches to the current value to be detected.
The top switch sets the tens digit, and the bottom switch sets the ones digit.
The default settings are followings: Setting switch (top row): 0
Setting switch (bottom row): 1
∗Example
of setting 12 A
Setting switch (top row): 1
Setting switch (bottom row): 2

±5%
(±20% for a rated load current setting of 20% or
less. See table at right for details.)
1.0 s max. (with ON/OFF control)
Note 1.
The alarm is output if the load current falls below the error detection
current.
2.
Take the detection tolerance into consideration in setting the error
detection current. (For details, refer to the
Heater Burnout Detection
Current Range
table at the right.)
3.
When using cycle control, heater burnout detection is possible at a
control cycle of 200 ms min. and an output duty of 50% min. (When
combined with the G32A-EA, heater burnout can be detected at an
output duty of 50% or higher.)
4.
When using cycle control, the detection time increases in inverse
proportion to the output duty.
5.
When used in combination with optimal cycle control (G3ZA), the
heater burnout detection function cannot be used.
6.
Do not set the heater burnout detection current to 0 A. Doing so would
cause constant detection of a SSR short-circuit failure when no
operation input is applied. Also, settings 4 to 9 on the top setting switch
are invalid. Do not set the switch to these values.
7.
The heater burnout detection function cannot be disabled. If it is not
needed, set it to the lowest setting (1 A).
8.
When the heater burnout detection level is changed, the new value
becomes effective immediately after the change. (The set value can be
changed in the G3PF even during operation.)
