What do the CBs in the JB20 do?
explanation of CB1, CB2, CB3 and up
RIH Panel Circuit Breakers
What CB1, CB2, and the Control Bypass switches (CB3 and up) do, how they should normally be set, and how to take a fluid out of bypass.
⚠️ Caution: Live Voltage
This panel contains live voltage. Only qualified personnel should open the panel or work inside it.
Breaker Reference
Supplies power to the RIH. Leave ON during normal operation.
Powers the solenoid valves for overhead reels such as oil, coolant, and ATF.
Each bypass breaker sits to the right of the relay it controls. When a bypass breaker is ON, its relay is bypassed and that fluid can be dispensed without authorization. Turn it OFF to return the fluid to normal authorized control.
| Bypass Breaker | Relay Bypassed | Fluid |
|---|---|---|
| CB3 | R1 | Fluid 1 |
| CB4 | R2 | Fluid 2 |
| CB5 | R3 | Fluid 3 |
| CB6 | R4 | Fluid 4 |
| CB7 | R5 | Fluid 5 |
Mapping shown matches Figure 1. The number of fluids and breakers varies by installation.
Power Cycle the RIH
1 | Turn CB1 OFF. |
2 | Wait at least 10 seconds. |
3 | Turn CB1 back ON. |
Take a Fluid Out of Bypass
1 | Find the relay for the affected fluid, then the bypass breaker immediately to its right. |
2 | If that breaker is ON, turn it OFF. |
3 | Confirm the fluid no longer dispenses without authorization. |
Still dispensing with bypass OFF?
If a fluid can still be dispensed without authorization while its bypass breaker is OFF, further troubleshooting is needed. Contact Fleetwatch Support.
