R2 R20 Power LED Not Lit
R2 R20 Modules Are Not Outputting As Expected
An R2 R20 module can be identified by it's yellow label on the front of the module:
The issue you may see in very specific circumstances with the these modules is that the signal light is on but the power LED is off. This situation can be remedied by flipping the breaker on the circuit but then the behavior may present itself again later.
