5.4 Setup Setting Mode
Setup setting mode is used to set the heater beak alarms, PV bias, digital filter, communication, and to lock the set data. The instrument
can be switched to AT start or AT cancel. Press the <R/S key while pressing the SET key with state of PV/SV monitor mode, SV setting
& CT monitor mode, or parameter setting mode to shift to this mode. The UP, DOWN or <R/S key is used to change the numeric value,
and the SET key is used to change the parameter as well as to register the numeric value.

Description of each parameter
Execution of autotuning (AT)
The AT function is executed to the control area now in operation.
Setting range: ON: AT start or execution OFF: AT end or cancel
Factory set value: OFF
•
The batch setting allows the autotuning to be executed simultaneously in all channels.
•
When instrument displays data without a channel, an AT lamp does not flash during AT
execution.
Heater break alarm 1 (HBA1)
HBA1 set value is set by referring to monitor value from the current transformer 1. Used for single-phase
or three-phase.
Displayed only for when the heater break alarm is selected as alarm 2.
Setting range: 0.0 to 100.0 A OFF: HBA1 function OFF
Factory set value: OFF
•
No setting can be changed when “1 (Lock)” is selected by the lock level 1.
•
HBA is not available on a current output.
•
Set HBA1 set value to a value about 85 % of current transformer 1 input value.
•
When power supply variations are large, set the HBA1 set value to a slightly smaller value. In
addition, when two or more heaters are connected in parallel, set the HBA1 set value to a
slightly larger value so that it is activated even with only one heater broken (However, within
the value of current transformer 1).
•
When no current transformer is connected in any setting other than “OFF,” the heater break
alarm is turned on.
Heater break alarm 2 (HBA2)
[Correspond to only MA900]
HBA2 set value is set by referring to monitor value from the current transformer 2. Used only for three-
phase. Displayed only for when the heater break alarm (Z-168) is selected as alarm 2.
Setting range: 0.0 to 100.0 A OFF: HBA2 function OFF
Factory set value: OFF
•
No setting can be changed when “1 (Lock)” is selected by the lock level 1.
•
HBA is not available on a current output.
•
Set HBA2 set value to a value about 85 % of current transformer 2 input value.
•
When power supply variations are large, set the HBA2 set value to a slightly smaller value. In
addition, when two or more heaters are connected in parallel, set the HBA2 set value to a
slightly larger value so that it is activated even with only one heater broken (However, within
the value of current transformer 2).
•
When no current transformer is connected in any setting other than “OFF,” the heater break
alarm is turned on.
•
In case of MA901, this setting item is not provided.
PV bias
Set the PV bias to add to measured value for sensor correction, etc. The PV bias is used to correct the
individual variations in the sensors or when there is difference between the measured values (PV) of
other instruments.
Setting range: -span to +span (Within -1999 to +9999 digits)
Factory set value: Temperature input 0
°
C [
°
F] or 0.0
°
C [
°
F] Voltage input 0.0 %
No setting can be changed when “1 (Lock)” is selected by the lock level 1.
Digital filter
Set the time of the first-order lag filter which rejects any noise contained in the measured input.
Setting range: 1 to 100 seconds OFF: Digital filter function OFF
Factory set value: OFF
No setting can be changed when “1 (Lock)” is selected by the lock level 1.
Proportional cycle time
Set control output cycle. For heat/cool PID action: Heat-side proportional cycle time
Setting range: 1 to 100 seconds
Factory set value
:
Relay contact output 20 seconds Voltage pulse output, triac output 2 seconds
•
No setting can be changed when “1 (Lock)” is selected by the lock level 1.
•
Not displayed for current output.
