The following steps will explain an example of how to set DI1 to switchover between standby
ON/OFF.
7-12
Digital Output
Each of DO1 to DO5 can be assigned the following functions (events). The functions are
divided into two categories for when they behave as alarms and when they behave as events.
1. DO event settings
Events are divided into those related to alarms and those not related.
For more about the events related to alarms, see "11. Alarm Action Type Codes" (page 18).
Use the following steps events other than alarms.
●
Ramp soak delay start
●
Wire burnout circuit alarm
●
Conditional outputs
Use the following steps to set DO.
2. Setting DO option functions
Allows you to set not just even settings, but option functions for each DO.
The DO events are set by each digit.
3. Setting the alarm menu
●
Hysteresis Function
The hysteresis band is preserved during alarm output.
●
Delay Function
When events (including alarms) occur, the DO does not begin outputting immediately.
Instead, the event continues for a specified period of time before outputting DO.

2
Display the DI1 parameter ("
di1
") and choose 1 ("

").
This chooses to switchover between standby ON and OFF.
3
Press the
key to set the value.
Caution
When “Switchover between local and remote” (DI setting value =3) is used for the
digital input function, the operation before turning off the power of the main unit
affects the DI operation when the power turns on again.
(For the DI operation when the power turns on under each state, see the table
below.)

Set the event you want to specify under the DO1 output event setting type
("
do1T
").
3
Set the option function under the DO1 option function parameter ("
doP1
").
For the contents of this setting, see "2. Setting DO option functions" below.

Function
Description
bit0
Event output latch function
Latches (maintains) the DO when the event starts
bit1
Error alarm function
Outputs when the unit receives an input error
(“
UUUU
” or “
LLLL
” is displayed).
Set DO event to “0” when using this function.
bit2
Non-excitation output alarm
function
Reverses the output signal and outputs it through
the DO terminal when the event starts
bit3
Hold reset function
When using an alarm with hold, the hold function
will reset when any of the following operations
occur:
SV change / Alarm type change / Alarm set value
change /Standby cancel / Power reset
bit0 (1 : ON, 0 : OFF)
