Display: This instrument displays the scaling range from over 110% to below −1%.
Output: When the input value exceeds the output range, the output is fixed to 0% FS and 100% FS.

Operation explanation:
Upper limit action/lower limit action

Accessories
Application

Precautions
Maintenance95

When the input exceeds or falls below the alarm setting value, the alarm output is turned on (off when non-excitation is set).

Upper limit action with standby/lower limit action with standby
 his is a function to refrain from alarm output even when the input at the time of turning on of power supply to the instrument isT
within the alarm action range.
Also, when the input enters the alarm action range due to the change of the alarm setting value during operation, the alarm will not
be output.
Then, once the input exceeds the alarm action point (alarm setting value), the standby function will be canceled.

In combination with our two-wire type fine differential pressure transmitter, short-circuit the terminals (10) and (19) with the suppliedshort-circuiting wire.
In this case, a separately installed DC power source is not necessary because our receiving instrument has a built-in DC powersource for two-wire type fine differential pressure transmitter.
