R1C supply voltage The required supply voltage for the R1C depends on the output signal configuration as described below. To remain compliant the R1C needs to be connected to a marked BEMS /EMS system or power supply and must be earthed.
R1C configuration Supply voltage required 4 - 20 mA output not used separate 9-30 Vdc, < 35 mA 4 - 20 mA output used separate 22-30 Vdc, < 35 mA

Trap operating correctly
Trap leaking steam
Trap blocked or waterlogged
Trap cold but free of condensate (this is a common state during system start-up or when the system is shutdown).
Note : During normal operation, the green light flashes ON every second to show that electrical power is connected to the R1C and that it is operating correctly.

Trap leaking steam detection period Internal switches in the R1C allow the trap leaking detection period to be set to 2, 22, 44 or 88 minutes.
Condensate conductivity levels Internal switches in the R1C allow the condensate conductivity detection level to be set to 17, 4.8 or 1.2 microsiemens depending on local conditions. In addition it can be disabled if required.

Trap waterlogging temperature levels Internal switches in the R1C allow the waterlogging temperature level to be set to: 48°C, 63°C, 85°C, 111°C, 140°C, 169°C or 191°C (118 °F, 145 °F, 185 °F, 232 °F, 284 °F, 336 °F or 376 °F). In addition it can be disabled if required. As supplied, the R1C comes factory set as follows: Channel Failure detection Notes Leak detection period 22 minutes
The trap must leak steam for 22 minutes before the R1C signals a fault.
The conductivity of the condensate in the sensor chamber must be greater than 4.8 microsiemens for correct operation. The condensate in the sensor chamber must cool below this temperature before the R1C signals a waterlogging fault.
