■ Connections
Measuring input terminals of the instrument and,
the contact output and auxiliary supply terminals M3.
Make firm and correct connections with crimp type terminal.
Optimum torque of the terminal screws: 0.36~0.48N･m
Note : In case that the model name is NRP-60H, no contact output
terminals for the low limit is provided.
● Measuring Input Terminals
Arrange a cabling of measuring input line and power source line as distant as possible from each other. Close and parallel wiring of
these two lines may cause unstable reading of the instrument.
① DC Volt Meter
DC Current Meter
Receiving Meter
Connect the measuring input with correct polarity.
Use the particular accessory when it is designated.
② AC Volt Meter
AC Current Meter
Connect the measuring input.
Use the particular accessory when it is designated.
● Auxiliary supply Terminals
① AC power source model ② DC power source model
Connect the AC voltage to the respective terminals of Connect the DV24V to the auxiliary supply
auxiliary supply terminals (SOURCE). terminals (SOURCE) with correct polarity.
AC100V power source voltage: Terminals ± and 100/110V
AC200V power source voltage: Terminals ± and 200/220V
● High Limit (HIGH) and Low Limit (LOW) Contact Output Terminals
The contact capacity of high and low limit contact output is, with resistive load: AC250V, 125VA or DC30V, 60W
Make the connections with the cable conforming to these capacities. In case that the relay controls with the capacity higher than
these, provide the auxiliary relay externally.
■ Operation
① Prior to the operation of instrument, check that the input rate, auxiliary supply voltage and connections are correct.
② Before starting the measurement, check if the measuring pointer is accurately at zero (which is the point when the DC4mA
or DC1V generated by a standard voltage/current generator is input to the input terminals, respectively when the rated input
is DC4~20mA or DC1~5V). If there is a discrepancy at zero, adjust the pointer to indicate zero with the adjuster provided
on the front of the instrument.
③ Turning the high (or low) limit setting knob, set the setting index at a desired point where the relay acts.
The setting index stops at slightly beyond the scaled range. If the setting knob is forcedly turned more, it causes a breakage,
so take care with it.
Note)
When the input impedance at the input rating DC1 ~ 5V with the specification of 7331 accessory having more than 1 MΩ is
inserted the auxiliary power with opened condition of input terminal of 7331, the measuring pointer indicates more than the
upper limit of the scale.
④ While the instrument is powered on and when the measuring pointer exceeds the setting index (set point), the relay is
actuated and, a-c turns ON (close) and c-b turns OFF (open).
