● Changing Switch Settings
Do not change the time unit, time scale, operating mode, or INIT/
TIME switch while the Timer is in operation. Doing so may result
in malfunction. Turn OFF the power supply before changing the
setting of any switch.

A voltage equivalent to the power supply voltage is also
applied to the input circuit.
input terminals of those Timers must be wired properly so that
they will not be different in phase or the terminals will be short-
circuited to one another. Always use the same power supply
phases.
noise, separate the Timer and input device as far as possible
from the noise sources. It is also recommended to shield the
input signal wiring to prevent electronic interference.

waveform according to JEC-210, Impulse Voltage/Current
Test, of The Institute of Electrical Engineers of Japan. Surge
or noise superimposed on the power supply may damage
internal components or cause them to malfunction. We recom-
mend that you check the circuit waveform and use surge
absorbers. The effects on components depend on the type of
surge and noise that are generated. Always perform testing
with the actual equipment.
