E.19 Energy Management System (EMS)
Adding the EMS allows a heater to operate
automatically, or to act as a weather station when part
of a network of heaters controlled by the Fastrax®
RCMS.
The system includes a module, a precipitation
detector, ambient temperature sensor, and rail
thermostat. Once installed, the controller recognizes
the EMS module and works in conjunction with it.
Controls:
NOTE:
These settings are true for AUTO mode only, with the
exception of the TEST switch.
These setting are overridden when operated in REMOTE
SCADA mode by the corresponding Fastrax
®
RCMS software
parameter.
1.
SNOW-RAIN :
1.1 This dial adjusts the temperature set point
between -12°C to +12°C.
1.2 Precipitation detected when the ambient
temperature is below this set point is
considered snow or above it is rain.
2. LOW TEMP :
2.1 This dial adjusts the temperature set point
between –55°C to +5°C.
2.2 The EMS will not request the heater to operate
when the ambient temperature is below this set
point and snow is detected.
3. DELAY ON :
3.1 This dial sets the length of the delay, 0 to 30
minutes, before making the heater request.
3.2 When snow is sensed continuously for the
duration of the delay on period the heater
request is made. If at any time during the delay
snow is not sensed the timer is reset.
4. DELAY OFF :
4.1 This dial sets the length of the delay, 0 to 60
minutes, before removing the heater request.
4.2 When snow is no longer sensed the heater
request is held for the duration of the timer. If
at any time during the delay snow is sensed the
timer is reset.
5. TEST:
5.1 This switch simulates precipitation when ON.
Used to test the module operation.
6. SENSITIVITY :
6.1 This dial adjusts the precipitation detector
sensitivity between the least, 1, and most, 6. For
example, when set at 1 the detector has to be
very wet to indicate precipitation.
7. INDICATIONS :
7.1 On the module are a number of status LED’s
intended to aid the user’s understanding of the
state of operation. See table for full description.
