T1
Timer
setting 1
0.0 to 99.59
Unit: minutes and seconds or hours and minutes
Set the timer time unit using parameter TTU.
For example, 15.25 sets 15 minutes and 25 seconds.
(T1 is for AL1, and T2 is for AL2)

(2) Operating Parameters : Parameters changed rather frequently during operation.
HC
Heater disconnection
current measured
value “HC” is not a parameter to be set. The current value (0 to 80) of heater disconnection
detector is displayed. Unit: A (ampere)
Settings: When the display value is – – – –, the heater current is not being measured.
A1
Alarm 1
setpoint
Max. value of
measured input range
(scale) (PV alarm)
A2
Alarm 2
setpoint
Min. value of
measured input range
(scale) (PV alarm)
0: No key lock
1: Prevents operations from being changed except for the
changing of SP in the operating display
2: Prevents all parameter changing operations
