Yokogawa Button Operated MV2000 - Manual (Page 23)

Connecting the input wires in parallel with other devices can cause signal
degradation, affecting all connected devices. If you have to make a parallel
connection, then
• Turn the burnout detection function OFF.
• Ground the instruments to the same point.
• Do not turn other instruments ON or OFF during operation. This can have adverse
effects on the other instruments.
• Do not connect RTDs in parallel.
Wiring Procedure
There is a terminal cover screwed onto the signal input terminal block on the rear panel.
It has a label indicating the terminal arrangement on it.
1. Turn the MV OFF and remove the terminal cover.
2. Connect the signal wires to the terminals.
R ecommended torque for
tightening the screws
Screw terminals 0.9 to 1.0 N•m
Clampted terminals 0.22 to 0.25 N•m
3. Replace the terminal cover and fasten it with screws. The appropriate tightening
torque for the screws is 0.6 N•m.
Note
It may be difficult to firmly secure input signal wires with diameters of 0.3 mm or less to clamp
terminals. To secure the wires, try folding the conductive parts over when you connect them to
the clamp terminal.
