From factory, Vext is connected to VCC.
To power the meter from an independent source, you will need to unsolder a jumper inside the meter. Once done, you can power the meter from an independent source.
OVP - Over Voltage Protection
The indicator will turn green when enabled and grey when disabled.
Factory defaults are 000.
The OUT arrow will point:
To reset the meter, move the arrow below LOP and click OK.
Power off the meter, click and hold the ok button and power up the meter.
Move arrow up past VOP and click OK.
This model is similar to the SIN9020S meter but has a current transformer for measuring current. This model also has the ability to trigger a relay in the event of low voltage.
All connections to the meter are made from the current capacitor board.
Connection | Description |
---|---|
Bat | Batter Monitoring Connection (10-90v) Meter will get power from this connection when jumper is set to J4. |
Relay +/- | Relay Connection |
Vext +/- | Power supply connection. When connecting a relay, this voltage will be used to trigger the relay. (10-60v) |
Jumper | J3 - Relay or Power Supply Connections J4 - No Relay or Power Supply Connections |
Note: Jumper should be set to J4.
Note: Jumper should be set to J3.
Note: Jumper should be set to J3.
