4. R1C commissioning
The R1C has internal switches which allow the following parameters to be adjusted:
1. Trap leaking detection period. This is the delay between a trap failing open (i.e. starting to leak
steam) and a warning being given by the R1C
2. Trap leaking detection levels. This is the conductivity threshold of the condensate required
for correct operation.
3. Trap waterlogging detection level. This is the condensate temperature at the sensor that will
trigger a waterlogging warning.
As supplied, the R1C is set as described in Table 5:
Table 5 R1C settings (as supplied)
Channel Setting Notes
Leak detection period 22 minutes
The trap must leak for 22 minutes before
the R1C signals a fault. See Table 6.
The conductivity of the condensate at the sensor
Leak detection level 4.8
m
S must be greater than 4.8 microsiemens for
correct operation. See Table 7.
Waterlogging detection
The condensate at the sensor must cool below
temperature
85°C this temperature before the R1C signals a
waterlogging fault. See Table 9.
The R1C’s modes of operation are configured with the DIL switches on the PCB.
Please note: the SW1 DIL switch 1 is the test switch which should be OFF for all normal trap
monitoring modes except the test modes described in Table 9.
