*1: Precautions for heater break alarm (HBA) setting
,#
Displayed only for when HBA is selected as second alarm.
,#
HBA is not available on a current output.
,#
Set HBA set value to a value about 85 % of current transformer input value (CT). However, when power supply variations are
large, set the HBA to a slightly smaller value. In addition, when two or more heaters are connected in parallel, set the HBA to a
slightly larger value so that it is activated even with only one heater is broken (However, within the value of CT).
,#
When the HBA set value is set to "0.0" or the current transformer is not connected, the HBA is turned on.
*2: Precautions for control loop break alarm (LBA) setting
,#
Displayed only for when LBA is selected as first alarm or second alarm.
,#
Usually set the set value of the LBA to a value twice the integral time (I).
,#
No control loop break alarm can be used at heat/cool PID control action.
,#
No LBA function is activated while the AT function is activated.
,#
The LBA function is activated only at the 0 % or 100 % of PID computed value. Therefore, the time from trouble occurrence till the
activation of the LBA function equals the time until the PID computed value becomes 0 % or 100 % plus the LBA setting time.
,#
If LBA setting time is too short or does not match the controlled object, the LBA may be turned on and off or not be turned on. In
this case, depending on the situation, change the LBA setting time.

Setting parameters other than set value (SV)
The setting procedures are the same as those of example (2) to (4) in the above "

key
after the setting end shifts to the next parameter. When no parameter setting is required, return the instrument to the PV/SV display
mode.
NOTE

,#
Even if the displayed value is changed, it is not registered. To register it, press the
SET
key.

If the key is not operated for more than 1 minute, the present mode returns to the PV/SV display mode.
Some parameter symbols may not be displayed depending on the specification.
