Back Panel of the FCS2 & FCS3 Controller

AC Power
line input, power switch, voltage selector, and fuses are all incorporated in the AC Power Input Module. The
controller can operate between 90 - 260V 50-60Hz, or a 24V battery can be used as an alternate power supply. The fuse
carrier contains two 0.5A slow blow fuses. The fuses can be accessed by prying the fuse block out of its socket with a small
screwdriver wedged under the small slot in the opening of the AC line receptacle. When replacing the fuse block, make sure to
align the arrow on the outside of the fuse block with the closest voltage value to your supply line voltage:
•
For 90-130 supply line voltage place the fuse block with the arrow pointing to 110-120V.
•
For 180-260 supply line voltage place the fuse block with the arrow pointing to 220-240V.
Temp Out
is a voltage output direct from two instrument amplifiers reading the thermistors from channel A and B.
The output from this socket is temperature / 10. 37.0°C = 3.70 Volt DC.
The left pin is channel A, center pin is channel B, and right pin is ground.
Remote Setpoint
is an analog input that allows the user to set the controllers setpoint from an external DC source. The sleeve is
earth ground. A DC voltage can be applied to the tip of this jack equal to temperature /10. i.e.: 28.5°C = 2.85 Volt. When the jack is
inserted into the controller it will automatically switch to the jacks value. When removed it will default to the setting on the front of
the controller. Use for programming or cycling operating temperatures.
Controller Operation:
1. Turn the unit on using the main on-off switch located on the rear panel. The Chamber need not be plugged in at this time.
All further adjustments are made on the front panel.
2. Set the display switch to the “SET” position. Insert the enclosed screwdriver into the hole marked Setpoint and adjust the
controller to the desired setpoint.
3. Set the display to the “Slide” or “Chamber” position. The LCD will display a number between -1.8 and -4.2. This is normal.
4. Press the black button labeled “CALIBRATE” and make sure the display reads 26.6°C when “Slide” is selected and 25.0
when “Chamber” is selected. If adjustment is necessary, turn the corresponding screws in the adjustment holes with the
enclosed screwdriver. CW = increase, CCW = decrease.
5.
Turn the controller off.
6. With the chamber loaded, plug the chamber into the controller.
DO NOT
plug the chamber into the controller unless it is
either loaded or both slide contact wires are restricted from coming in contact with the base.
7. When the controller is turned on and the display switch is set to “Slide” or “Chamber” it will read the ambient temperature,
then slowly begin to rise until it reaches setpoint temperature. We recommend leaving the display switch in the “Slide”
position because it is the closest representation of the cell temperature.
Special Notes:
There is a safety cut-off circuit that protects the cells if the microaqueduct drops below 0.9°C from the setpoint after reaching
setpoint minus 0.9°C. Only during a cold start will the safety cut-off circuit ignore the out-of-range condition. This safety circuit
will shut off power to the slide circuit only and sound the alarm. If the alarm sounds, the user should correct the problem and
press the red reset button located next to the red LED.
