Parallel input
This device contains the following inputs for the parallel interface. After you enable outside
input operation (See "5.2.1 Setting EXT I/O IN" (page 79) ), the following operations can be
controlled with the inputs.

Parallel Signal Input
Note
Do not connect a live contact to the input terminal. Doing so will cause malfunctions.
For each operating action, see "5.11 Action" (page 105).
When multiple signals are sent at the same time, the inputs are given the following priority:
(1) Cleaning (2) Alarm check setting (3) Zero calibration (4) SAMPLING START. Any other inputs
entered at the same time are reserved.
Parallel inputs that are signaled for fewer than 3 seconds may not be registered by the device.
Make sure that an ON signal is sent for at least 3 seconds to guarantee proper operation.
