Rs-232C Connector; Connecting The Dc Power Supply Input Terminals; Attention - KYOWA WP-120A Instructions For Use Manual

3. Making connections
Start/stop measurement
When "MEASURE. START. COND. " or "MEASURE. STOP. COND. "
is set to "EXT. SIGNAL" on the WORK settings screen, this
controls starting and stopping measurement.
Select the control method with EXT. START/STOP (page 67).
When set to "EDGE", measurement will start or stop when it
switches from OFF to ON.
When set to "LEVEL", measurement will start when it
switches to ON and stop when it switches to OFF.
Zero balance displacement
Setting this to ON zero-balances the displacement sensor.
Digital zero
Setting this to ON sets the digital zero (page 15).

3-8. Connecting the DC power
supply input terminals
The DC power supply input voltage should be 24 V ±10%.
Use a power supply cord that is 0.517–2.081 mm
When connecting to the terminal bank, use a solderless terminal
(M3, width of 6 mm or less).
ATTENTION
o If using the unit as a CE compliant product, the power cord
must be no more than 3m long.
o Allow the unit to warm up for at least five minutes after
supplying power to it.
o The recommended tightening torque for terminals is 0.5 N·m
(5.1 kgf-cm).
V Always attach the cover to the power supply input
terminal bank. Failure to do so could result in fire,
electric shock or malfunction.
V Use a power supply that conforms to a limited energy
circuit as specified in IEC61010-1. Failure to do so
could cause fire or other hazards.
