E.3 Controls
1. Power: This switch turns the power supply to the board
‘ON’ or ‘OFF’.
WARNING
WARNING. 120V AC inputs to controller can remain
energized.
2. Reset: This push button is used to reset the controller in
case of a lockout.
3. Delay Start: This dial sets the length of the delay, 0 to 60
seconds, before starting the heater. It is intended to allow
the stagger start of multiple heaters connected to one
power service thereby reducing the maximum current
draw. This setting is true for REMOTE RTC mode only.
Under MANUAL, AUTO and REMOTE SCADA modes
there is no delay.
NOTE: This setting is overridden when operated in REMOTE
SCADA mode by the corresponding Fastrax® RCMS
software parameter.
4. Post Purge: This dial sets the length of the delay, 5
seconds to 4 minutes, once the heater is no longer
requested, before stopping the fan. It is intended to purge
the remaining heat and moisture from the combustion and
duct system. This setting is true for all modes.
5. RTC Time: (RTC stands for Rail Traffic Control dispatch)
This dial limits the run time between 20 minutes to 4 hours,
when requested by RTC dispatcher, and with the RTC
SW switch ON, and the heater is in REMOTE RTC mode.
When the RTC request exceeds the time limit, the heater
turns off, and the run indication is maintained as long as
the heater is requested.
Timer is reset once the RTC request is removed. RTC can
then request the heater for another cycle.
It is intended to save fuel by avoiding unnecessary heater
operation by the dispatcher. This setting is true for RTC
MODE only. Under MANUAL, AUTO, and REMOTE SCADA
modes there is no limit.
6. RTC SW: This switch enables the RTC TIME function when
in the ON position. When switched OFF, RTC TIME is
disabled and the heater runs as long as requested.
7. JUMPER, JP1: Used to configure controller parameters.
E.4 Indications
1. On the controller are a number of status LEDs intended
to aid the user’s understanding of the heater state of
operation. See Table 6 - Controller LED Descriptions for
full description.
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.
2. Refer to Section F - Troubleshooting for explanation of
problem condition LED codes.
3. The LEDs listed can be found on the controller from top
left to bottom right on the board.
