EGG STATION (ES-600 & ES-1200)

Control Board LEDs

The Control Board has three onboard LEDs (Figure
5) to determine the status of the unit and to assist in
troubleshooting.
Green (Diagnostic): The LED should be off in normal
operation however, if any of the 5 potential faults are
detected by the Control Board, this LED will repeatedly
blink either 1 through 5 times with a 2 second pause in
between (refer to the Green LED Blink Codes section
below).
Yellow (Audio): When lit, This LED indicates that the
Control Board is supplying approximately 10-15 VDC to
the audio signal. The audio signal should sound when
this LED is lit.
Red (Heat): When lit, this LED indicates that the
Control Board is calling for heat by supplying VDC to
terminals 3(+) and 4(-) of the Solid State Relay. When
off, it means that the grill platen is up to operating tem-
perature and satisfied

NOTE: During heat mode, this Red LED is very dim,
so it may be difficult to verify if the Control Board
is, or is not, calling for heat. It is recommended
that you observe the small round green LED on the
Solid State Relay (Figure 6)for mode and diagnostic
purposes. When the green LED on the Solid State
Relay is on, it means that the Control Board is call-
ing for heat. When off, it means that the Control
Board is NOT calling for heat. Typically, the VDC at
the Solid State Relay will be less than 1.0 VDC when
measured, but may vary because of different quality
VOMs. Therefore, it is recommended that you DO
NOT attempt to measure the VDC at the Solid State
Relay for diagnostic purposes.
Condition
In this state, the unit turns off the control signal to the solid
state relay and disables all front buttons and lights. The unit
will not heat up. This continues until the defaults are reloaded
into memory. To reload the defaults, turn the unit off, press and
hold the Time 2 button, turn the unit back on, and release the
button.
In this state, the unit turns off the control signal to the solid
state relay and disables all front buttons and lights. The unit
will not heat up. This continues until the ambient temperature
within the electrical compartment drops below 140º F (60º C)
and the unit is turned off and back on.
In this state, the unit turns off the control signal to the Solid
State Relay and disables all front buttons and lights. The unit
will not heat up. This continues until the Thermocouple is
reconnected or replaced, and the unit is turned off and back
on.
In this state, the unit turns off the control signal to the Solid
State Relay and disables all front buttons and front lights. The
unit will not heat up. This continues until the supply voltage is
within the proper limits and the unit is turned off and back on.
In this state, the unit turns off the control signal to the Solid
State Relay and disables all front buttons and lights. The unit
will not heat up. This continues until the 50/60 Hz signal is
reapplied and the unit is turned off and back on.
