If the A/M Key is pressed to switch to the manual output mode, a dis-
play like the following will appear and the MANU indicator will light.

Balanceless-bumpless function prevents sudden changes in output
values when the mode is changed.

Note:

1. Balanceless-bumpless function will not operate in the

ON/OFF operating mode or when I is set to zero.

Alarm 1, 2 : 

al–1

 , 

al–2

When 

al–1

  or  

al–2 

 (or 

al

) is displayed on the PV display, the alarm

value for alarm output can be set on the SV display. When the value
exceeds or falls below the set alarm value, the corresponding alarm
output is produced and the ALM indicator on the front panel lights.
Usually, the alarm value is set as a deviation from the set value, but it
can also be set as an absolute value when the event alarm mode is
selected. Set the alarm value by using the Up and Down Keys while

al

 is displayed. The message is not displayed if the alarm mode se-

lector is set to position 0. Factory-set to upper-limit, alarm value 0.0.

Input Shift: 

in–5

Set the input value by using Up and Down Keys while 

in–5

 is dis-

played.

This function can be used mainly for fine tuning compensation,
while leaving the set value unaffected. Select this function by press-
ing the Display Key three times in display level 0, as shown below.

Note:

ON) or current output (SW202 ON).

2. Not displayed in PID with feed-forward control cir-

cuit (SW201 pin 1 OFF). (However, if P is 0, the dis-
play will appear.)

3. Not displayed when the alarm 1 and 2 are disabled

(SW205 set to 0, and SW203 set to 0 or 9)

If the input range is changed so that the main setting no longer lies
within it, the set point will automatically be changed to 

inl

. If main set-

ting stays within the range, the set point will remain as it is.

If 

inl

 is set to a value greater than or equal to 

inh

inl

 will automatically

be set to 

inh

 + 1.

If 

dp

 is set to 3, the leading zero will not be displayed for negative

values, e.g., –0.023 will be displayed as –.023.

Set 

inl

 and 

inh

 so that the difference between them (i.e., the resolu-

tion) is 5,000 or less. Otherwise, the display may not function prop-
erly.
