E.10 Activating MODE Parameter
NOTE: Read and understand the following procedure before
starting.
1. The controller must be powered on for a minimum of 60
seconds, the mode selector switch toggled OFF, and
terminals A1 A2 open (i.e. no RTC request).
2. Short jumper JP1. The RUN indication relay and LED
pulses on and off. After five RUN indication pulses, the red
ALARM LED lights for 3 seconds. This cycle continues as
long as the jumper, JP1, is shorted.
3. Count the number of times the red ALARM LED lights.
4. Once the count equals the parameter number, remove
the jumper before the ALARM LED turns off. For example,
when the ALARM LED lights for the second time removing
the jumper will activate FAN MODE DISABLE, parameter
#2.
5. Function performed.
6. Parameter or new address is stored on the EEPROM.
7. Repeat sequence as required to activate other parameters.
E.11 Fan Mode
1. When enabled for continuous operation, this mode can
be beneficial for locations with difficult to detect drifting
snow conditions that cause snow accumulation in the
turnout and or in the duct system.
2. When enabled, and with the mode selector switch in either
the MANUAL or REMOTE/AUTO position, the fan will run
continuously, with heating requested or not.
NOTE: The fan will stop when the mode selector switch is in the
OFF position.
3. This parameter can be set, either, locally, or remotely by
the RCMS software.
4. Refer to RCMS documentation for remote activation.
E.12 Local EMS Mode
1. This parameter enables the locally installed EMS module
to control the heater according to the module set points.
If connected to a SCADA system, all weather data will be
transmitted to the system. No other functions are affected
by this mode.
2. The HEAT LED pulses to indicate that the local EMS
module can turn on the heater.
3. When disabled, the HEAT LED will not pulse. It will light up
when conditions are met, but it will not turn on the heater.
E.13 RAIL THERMOSTAT Mode, Normal
1. With the introduction of the 2014 model Hellfire, the rail
thermostat operation was reversed. The thermostat now
opens when cold and closes when warm.
2. When enabled, the controller is configured to operate with
the new, close on rise (COR), thermostat.
E.14 RAIL THERMOSTAT Mode, Reverse
1. When enabled, the controller is configured to operate
with the previous, open on rise (OOR), thermostat.
E.15 Failure Shutdowns and Alarm Indications
1. In the event of a failure, the controller ceases the heater
operation and indicates alarm.
2. While the heater is shutdown and indicating alarm the
controller continues communications with the RCMS
software. All start requests, local or through the RCMS
software, are ignored until the problem is resolved.
3. The controller indicates the nature of the failure in three
ways. LED’s on the controller, an alarm contact closure,
and error codes communicated via the RS-485 serial port
when under RCMS control.
NOTE:
With the exception of the communications TD, RD, and
TX LED’s. Solid green, solid green with a red pulse, or
yellow LED’s indicates normal status. Solid red and
alternating LED’s indicate a failure. This is true for the
controller only, not the EMS module.
4. There are two types of failure alarms, minor and major.
Both cease the heater operation, however, minor alarms
clear when the condition that caused the failure rectifies
itself. Major alarms, which are more serious and require
inspection, must be manually reset.
E.16 Fault Conditions
1. A failure exists when the STATUS and the ALARM LED’s
are solid red.
2. In addition, an alternating LED of equal duration on and off,
or red and green indicates the failure condition.
3. Heaters connected via the RS-485 port to a network and
RCMS software will communicate fault codes.
