¶ Wiring a Circuit Breaker Remote Trip
Warning: If powering an expansion board it should be at the same Voltage as the WatchMon.
Warning: For large (or unknown) loads make sure you use an external relay / SSR (solid state relays) that is appropriate for the rated purpose.
¶ Options for Wiring include
- Wiring to WatchMonCORE Onboard Relay A
- Wiring to Expansion 3 Board Relay 1, 2 or 3
- Wiring to Expansion 3 Board Solid State Relays 5, 6 and 7
- Wiring to Expansion 2 Board Relay 1 or 2
- Wiring to Expansion 2 Board Solid State Relays 3 or 4
- Wiring to WatchMon 4 or WatchMonPlus Onboard Mosfets A or B (5 Pin) *NOT RECOMMENDED
- Wiring to WatchMon 4.2 or WatchMonPlus or earlier onboard Mosfets A or B (4 Pin) *NOT RECOMMENDED
Note: Below diagrams apply to WatchMon 1, WatchMon 4, WatchMonCORE and WatchMonPlus
¶ Limitations
With a 48V circuit breaker and an external relay appropriately sized, Mosfets that can handle 48V on either the WatchMon or Expansion 2 or Expansion 3 Solid State Relays 60V / 5A can be used.
The Mechanical Relays on Expansion 2 and Expansion 3 are rated to 30V / 5A only.
Expansion board if powered should be at the same voltage as the WatchMon.
¶ 1. Wiring to WatchMonCORE Onboard Relay A
Note: Relay 1 and Relay 2 are mechanical and rated to 30V / 5A
¶ 2. Wiring to Expansion 3 Board, Relay 1, 2 or 3
Note: Relay 1, 2 and 3 are mechanical and rated to 30V / 5A
¶ 3. Wiring to Expansion 3 Board Solid State Relays 5, 6 and 7
Note: Relay 5, 6 and 7 are Solid State Relays and hence rated to 60V / 5A
¶ 4. Wiring to Expansion2, Relay1 or Relay2
Note: Relay 1 and Relay 2 are mechanical and hence rated to 30V/5A
¶ 5. Wiring to Expansion2 Board, Solid State Relays 3 or 4
Note: Relay 3 and Relay 4 are Solid State Relays and hence rated to 60V / 5A
¶ 6. Common Positive Sense Schneider Electric Circuit Breaker to On-Board WatchMon - Pin 5
Note: Mosfets are used for onboard outputs on WM 4 / 5 / 7. The 5 pin output version includes a Output P for Power and this is attached to the Positive.
Warning: Mosfets should only be used with items of known in-rush within the rating of the mosfet. If unsure please use a relay.
¶ 7. Common Positive Sense Schneider Electric Circuit Breaker to On-Board WatchMon - Pin 4
NOT RECOMMENDED
Note: Mosfets are used for onboard outputs on WM 4 / 5 / 7. The 4 pin output version doesn't include a Output P for therefore the battery Positive is used.
Warning: Mosfets should only be used with items of known inrush within the rating of the mosfet. If unsure please use a relay.
¶ Set Expansion Settings
Set Output to Critical Pulse OFF so that if in Critical state it will get a 2000ms pulse sent when Critical State turns to OFF used to trigger Circuit Breakers
If using a sensing input the input should be set to Critical contact sensor.
