BEMS/EMS to indicate steam trap status remotely. To detect a steam trap that is leaking steam, the R1C is used in conjunction with a Spiratec sensor chamber or steam trap fitted with a standard SS1 Spiratec sensor.

WLS1 waterlogging sensor assembly must be fitted. Note that the R1C will only work with Spiratec WLS1 sensors which do not have built in diode packs. WLS1 waterlogging sensor assembly with integral diode packs should not be used.

3.2.2 BEMS / EMS to R1C Wiring We recommend that the R1C is connected to the BEMS /EMS via a 6 core 7 /0.2 mm cable. The cable must be installed in steel conduit. Note: To ensure no loss in performance of the R1C, other power cables should not share the same conduit.

Off. NPN open collector outputs. Use this output option to connect the R1C to a B /EMS whose digital inputs are pulled-up to a positive voltage: The npn outputs act like switches connected to 0 volts. During normal trap operation, the npn outputs will switch On, giving out 0 volts with an output resistance of 220 ohms.

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.

BEMS /EMS set-up mode - the R1C will cyclically change it’s outputs, one step every 8 seconds. 5. BEMS /EMS commissioning An analogue output is available from the R1C as standard for use with BEMS /EMS’s that operate on an analogue input signal. Recommended BEMS /EMS setting details are given below:...

If the green light is not flashing, there may be a problem with the R1C. The R1C will show a failure for as long as the fault is present. If the R1C detects a transient fault, it will show the failure for at least one minute.
