HEAT - Amber
This LED is on steady when the controller is supplying 100% heat. The HEAT
LED is off when the controller is not supplying any heat. The HEAT LED
flashes when the controller is controlling the temperature inside the heat PID
proportional band.
HEAT ENABLE - Green
This LED is lit whenever the controller is on and conditions are proper for
allowing heat to be supplied to the fluid.
The following conditions are needed for the HEAT ENABLE LED to light.
1.
ON/OFF
mode must be
ON
2. There is no high temperature condition
3. Pump signal on
COOL - Green
This LED is on steady when the controller is supplying 100% cooling to the
fluid. The LED is off when the controller is not supplying any cooling to the
fluid. The LED flashes when the controller is controlling temperature by
cooling inside the cool PID proportional band.
PUMP - Green
This LED indicates the status of the pump control logic.
In the REMOTE mode, the LED is lit whenever the pump on signal from the
tool is on and the controller ON/OFF status is ON. 24VDC must be supplied
to pin 10 of P1.
In either the LOCAL or REMOTE mode, pressing the control ON button will
turn on either the LOCAL or REMOTE LED (whichever has been previously
selected). Pressing the controller ON button again will turn both the LOCAL
and REMOTE LED off.
NOTE:
The machine circuit is interlocked to the electrical enclosure so the
removal of the panel will turn off the unit and the controller.
LOCAL - Green
This LED is lit whenever the controller is in the local mode and is off when the
controller is in the remote mode, as selected by the
LOC/REM
key (ON mode
only).
REMOTE - Green
This LED is lit whenever the controller is in the remote mode and is off when
the controller is in the local mode, as selected by the
LOC/REM
key (ON
mode only).
FLUID LEAK
- Amber
This LED is lit whenever a leak is detected by the controller.
LEVEL FAULT - Amber
This LED is lit when the controller detects two gallons remaining in the tank.
When a low level condition is detected the controller disables the heater and
turns off the HEAT ENABLE LED. Once the condition is corrected it must be
cleared with the
RESET
key before the heater will be enabled.
