7.3 Initial Setting Menu
Display flowcharts in Initialization mode are shown in the following.
Do not change to the section parameters and any parameter in
the Initialization mode which is not described in the initial setting
menu below. It may result in malfunction or failure of the instrument.
7.4 Input Type Selection (SL1)
When any parameter setting is changed in the Initialization Mode,
check all parameter set values in SV Setting Mode and Parameter
Setting Mode.
Factory set value varies depending on the input type.

Conduct setting so as to meet the instrument specification (input type).
Setting change between different symbols may cause malfunction,
but the setting can be changed when hardware types have the same
symbol. However, when the setting is changed, always reset “SLH”
and “SLL” (See page 8).
 Change Settings
Example: Change the input type from “K” to “J”
1. Press the SET key. The display will go to SL1.
2. Press the UP key to change the number to 1.
3. Press the SET key to store the new set value.
The display goes to the next parameter.
7.5 Temperature Unit and Cooling Type
Selection (SL2)
Inappropriate settings may result in malfunction. Control type between
Heat Only and Heat/Cool cannot be changed by this parameter.
Factory set value varies depending on the instrument specification.

7.6 Alarm 1 [ALM1] Type Selection (SL4)
Alarm 2 [ALM2] Type Selection (SL5)
If the alarm function is not provided with the instrument when shipped from the
factory, no alarm output is available by changing SL4 and/or SL5.
SL4 is set to 0000 in the following cases.
• When the instrument does not have ALM1 output
• When Control Loop Break Alarm (LBA) is provided and assigned
to ALM1
SL5 is set to 0000 in the following cases.
• When the instrument does not have ALM2 output
• When Control Loop Break Alarm (LBA) is provided and assigned
to ALM2
• When the SV alarm is provided and assigned to ALM2
• When the Heater Break Alarm (HBA) is provided
Factory set value varies depending on the instrument specification.

* Hold action:
When Hold action is ON, the alarm action is suppressed at start-up or the
control set value change until the measured value enters the non-alarm range.
 Alarm action type
Both of the Alarm 1 and Alarm 2 outputs of this instrument are turned on when
burnout occurs regardless of any of the following actions taken (High alarm, low
alarm, etc.). In addition, when used for any purposes other than these alarms
(event, etc.), specify the Z-124 specification (not to be forcibly turned on).

Example: Change the ALM1 type from “Deviation high alarm (0001)” to
“Deviation low alarm (0101)”
1. Press the SET key three times at SL1 until SL4 is displayed.
2. Press the shift key to high-light the hundreds digit.
3. Press the UP key to change the number to 1.
4. Press the SET key to store the new set value.
The display goes to the next parameter.
7.7 PV bias (Pb)
The value set in the PV bias is added to the input value (actual measured
value) to correct the input value. 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: Temperature input: −1999 to +9999 °C [°F] or
−199.9 to +999.9 °C [°F]
Voltage/current inputs: −199.9 to +200.0 %
Factory set value: Temperature input: 0 °C [°F] or 0.0 °C [°F]
Voltage/current inputs: 0.0 %
