8 Test mode
Test mode is equipped with features that can be utilized, such as during start-up of equipment.
(1) Input wiring check
The connection state of voltage input and current input can be check.
Displays each phase of the active power value, and phase sequence of voltage.
Therefore, it will easily determine the mistake of connection of input.
Display example (3 phase 3 wire)
Main-monitor:Positive phase sequence "
" (Positive),
Negative phase sequence "
" (Negative),
Display when no input:"----"
(In case of 3φ4W, 1φ3W,
1φ2W circuit:"----")
Sub-monitor (left) :L1 phase of active power
Sub-monitor (right):L3 phase of active power
<Note> All connection mistake can not determine.
[Positive phase sequence] [Negative phase sequence]
(2) Contact output check
Measurement (voltage, current) with no input, can check the operation of pulse
output and alarm output.
The operation of contact output 1 can be check by the "321".
The operation of contact output 2 can be check by the "322".
〔Pulse output〕
『0FF (oFF)』
:Pulse output OFF
『ON (on)』 :Pulse output (pulse width 250 ms) is output every
second. And also displays the number of output pulses.
〔Alarm output〕
『0FF (oFF)』
:Contact OFF
『ON (on)』 :Contact ON
Switch the 『0FF (oFF)』⇔『ON (on)』in the【SET】
switch.
Please use it, such as the connection confirmation of the connection destination.
