OTT Pluvio 2 S - Page 40

Orifice rim heater self-test failed/is not run
䊳
Orifice rim heater supply voltage is missing, incorrectly connected, or is outside
the specified range:
➝ restore power supply to the orifice rim heater (replace fuse as necessary);
➝ check supply voltage level and adjust as necessary;
➝ check wiring of the orifice rim heater and correct as necessary.
䊳
Pipe housing (including built-in orifice rim heater) is not installed:
➝
install the pipe housing.
䊳
Pipe housing without built-in orifice rim heater of another OTT Pluvio
2
S
is
accidentally installed:
➝
install the pipe housing with built-in orifice rim heater.
䊳
No self-test is run:
➝ check the “Self-test interval” (Modes 2, 3, 4) setting and correct as
necessary (using the OTT Pluvio² Operating Software);
➝ force self-test by a “Power-Reset” once.
Orifice rim heater does not work/does not work as expected
䊳
Orifice rim heater supply voltage is missing, incorrectly connected, or is outside
the specified range:
➝ restore power supply to the orifice rim heater (replace fuse as necessary);
➝ check supply voltage level and adjust as necessary; make sure that output
power of power source is sufficient;
➝ check orifice rim heater wiring and correct as necessary; make sure that
cable cross-section is sufficient;
➝ check heater status (using the OTT Pluvio² Operating Software).
䊳
Pipe housing (including built-in orifice rim heater) is not installed:
➝ install the pipe housing.
䊳
Pipe housing without built-in orifice rim heater of another OTT Pluvio² S is
accidentally installed:
➝ install the pipe housing with built-in orifice rim heater.
䊳
Configuration of the orifice rim heater results in unexpected heater
performance:
➝ check settings
– mode of operation
– orifice rim target temperature (modes #1, #2, #3, #4)
– lower temperature limit (mode #2)
– switch-on time (mode #3)
– on-time (mode #3)
– after-run time (mode #4)
and correct as necessary (using the OTT Pluvio² Operating Software).
䊳
OTT Pluvio² S system time is incorrect (e.g. after power supply failure):
➝ correct system time (using the OTT Pluvio² Operating Software).
