Power
Depressing the Power button will switch the control power on or
off. When the Power button is pushed the microprocessor initi-
ates a diagnostic routine to determine if a brownout has
occurred. The Power button must be pushed to initiate control
power before either the Start button or remote on/off contacts
can start the unit.
Start
Depressing the Start button will start the pump and enable the
microprocessor control functions and initiate an Auto-vent
sequence.
The Auto Vent sequence is designed to remove air from the
water circuit of the process equipment. For the first 30 seconds
of the sequence the cooling valve is opened to allow air to
escape. After this, the valve is left open and the pump is ener-
gized for the remaining 30 seconds of the sequence to further
remove air from the system.
Stop
Depressing the Stop button will stop the pump, stop any Auto
Tune sequence, clear all faults and suspend the microprocessor
control program.
Purge
Pressing the Purge button will open the cooling solenoid or
modulating valve. This feature is designed to allow the mold
circuit to be purged of water with compressed air. It will only
function if the power is on but the heater and pump are off. This
feature should be used only after pressing the Stop button. The
external valves and associated parts required for compressed
air connection are an available option from our parts
department.
Alarm Silence
The Alarm Silence button is only functional if the Alarm Horn
option and/or Remote Alarm Contact option has been
purchased. If the Alarm Horn option has been purchased,
depressing the Alarm Silence button will disable the horn. The
horn will not reactivate until the alarm has been reset and a
subsequent alarm has been triggered. If the Remote Alarm
contacts option has been purchased, depressing the Alarm
Silence button will open the contact that was closed when the
alarm occurred. The contact will not close again until the alarm
has been reset and a subsequent alarm has been triggered.
Lower Set Point Temperature
Depressing and then releasing the Lower Set Point Temperature
button will decrease the set point temperature by 1°F (or 1°C). If
the Lower Set Point Temperature button is held down, the set
point temperature will continue to decrease until the button is
released or the minimum allowable set point temperature is
reached.
Raise Set Point Temperature
Depressing and then releasing the Raise Set Point Temperature
button will increase the set point temperature by 1°F (or 1°C). If
the Raise Set Point Temperature button is held down, the set
point temperature will continue to increase until the button is
released or the maximum allowable set point temperature is
reached.
Low Pressure
The Low Pressure LED will be illuminated if the inlet cooling
water pressure drops below the set point of the low-pressure
safety switch. If a low-pressure condition occurs, the unit will
automatically stop and remain de-energized until the cooling
water pressure rises back above the cut-in set point of the
pressure switch.
High Temp Safety
The High Temp Safety LED will be illuminated if the To Process
temperature exceeds 260°F (127°C). The High Water
Temperature LED will turn off when the water temperature is less
than 260°F (127°C). This fault will stop operation of the unit. To
clear this fault after the fault condition has been corrected,
depress the Stop button; restart the unit by depressing the Start
button.
Pump Motor Overload
The Pump Motor Overload LED will be illuminated if the motor
overload opens. This fault will stop operation of the unit. To clear
this fault after the fault condition has been corrected, depress
the Stop button; restart the unit by depressing the Start button.
