Rev. 004 SAFETY OVERVIEW FTS designs and manufactures units to be safe and reliable systems. Safety features are incorporated throughout and appropriate signs and symbols are provided. In this manual, safety issues are addressed in context. Users are strongly encouraged to become familiar with these symbols.
FC Series w/ EDC Control Thermal MNL-047-A Division Rev. 004 INSTALLATION Physical Location The area where you place the unit should be smooth, level, and capable of safely supporting the weight of the machine. Space should be provided so that air can properly circulate around the unit. If obstacles are blocking the airflow, the compressor may overheat.
FC Series w/ EDC Control Thermal MNL-047-A Division Rev. 004 OPERATION System Preparation 1. Plug the provided Pencil Sensor (RTD) into the jack labeled SENSOR on the back of the machine. 2. Place the sensor so that the shaft is in contact with the fluid / vapor whose temperature is to be controlled.
FC Series w/ EDC Control Thermal MNL-047-A Division Rev. 004 PROBE AND DELIVERY LINE Delivery Line Flexi-Cools have a delivery line that carries the refrigerant to the probe and back. This flexible delivery line is made of corrugated stainless steel tubing. Although this line is strong, it can be damaged to the point of rupture if it is repeatedly bent too sharply or forcibly twisted.
FC Series w/ EDC Control Thermal MNL-047-A Division Rev. 004 USER MENU This unit is equipped with an EDC digital control package. Varying the parameters in the EDC Controller’s User Menu allow the operation of the unit to be fine tuned to meet the needs of a specific application. A variety of parameters such as Ramp Rate, Auto-Power Recovery, High and Low Temperature Alarms, Parameter Lock, Setpoint Limits, readout options, Proportional Control parameters, and several Communications options can all be adjusted from the User Menus.

FC Series w/ EDC Control Thermal MNL-047-A Division Rev. 004 PROPORTIONAL CONTROL MENU Programmed transition rate from old setpoint to new setpoint, in degrees per minute. Ramp Rate is more of a slew limiter, because the available ramp rate is obviously limited by the Ramp Rate thermal load and the pulldown capacities of the refrigeration system.

(HA), or adjust the HA value so that it is above the desired setpoint. If the HA still goes off, check that the thermal load being applied by your process is within the heat removal capacity of this unit. Contact the FTS Service Division if the condition persists.
Then either increase the temperature setpoint to ensure it is set above the low temperature alarm setting (LA), or adjust the LA value so that it is lower than the desired setpoint. Contact the FTS Service Division if the condition persists. Stone Ridge, NY USA...
FC Series w/ EDC Control Thermal MNL-047-A Division Rev. 004 MAINTENANCE Warning! Hazardous voltages. Risk of electric shock. Disconnect all power before servicing this unit. Refer servicing to qualified service personnel. Notice! Only qualified personnel should perform maintenance on the refrigeration system itself, and only EPA certified technicians may evacuate or charge refrigerants.
FC Series w/ EDC Control Thermal MNL-047-A Division Rev. 004 CLEANING Warning! Hazardous voltages. Risk of electric shock. Disconnect all power before servicing this unit. Refer servicing to qualified service personnel. Notice! Only qualified personnel should perform maintenance on the system. Caution! Proper safety equipment such as eye and face protection, gloves and dust mask should be used.
Clean condenser, Fan not working Check for operation of fan (you can feel air being drawn across the condenser). If it isn't working, contact FTS Service. Compressor High pressure in the refrigeration Wait several minutes and try fails to restart system starting the unit again.
FTS WARRANTIES AND SERVICE AGREEMENTS The FTS Service Division was founded in January of 1971. Our technicians are fully trained to service all electrical, refrigeration, liquid, vacuum, air, and vapor control systems manufactured and sold by FTS. We service all FTS products throughout the world from our home office located at the FTS manufacturing facility in Stone Ridge, New York.

If your system is eligible for coverage, please review this warranty thoroughly and contact the FTS Service Division with any questions you may have. If your system is not covered by our standard warranty, or you are seeking optional or additional coverage, see sections below for service plans offered.
Page 23
This plan provides our customers with one or two onsite visits per year. We would perform a thorough preventative maintenance on your FTS equipment. You will be provided with a PM checklist and a certificate of calibration, which is traceable to N.I.S.T. The purchase of this plan also provides discounted parts and labor rate for additional service if deemed necessary at the time of the PM.
Page 24
Before working on systems that are not under warranty, the Service Division will provide you with an estimate of the time and cost for the repair of your unit. No work will be started until FTS receives a hardcopy of your purchase order for the repair work. This also applies to warranty work when the customer is responsible for the shipping costs.
EDC RS232 PROGRAMMER’S REFERENCE OVERVIEW The MPC and EDC controllers are used in a variety of cooling products manufactured by FTS, Inc. The commands used by a specific system will vary per the descriptions at the end of this reference, but the operational aspects, hardware and software, of the interface are consistent across the product line.
Page 26
FC Series w/ EDC Control Thermal MNL-047-A Division Rev. 004 COMMUNICATION DATA All programmable, selectable, or switchable functions of the target system are accessible via the RS-232, with the exception of the RS-232 configuration itself, which may not be programmed from the host. All data, programmed values, status, and system errors are accessible by the host, i.e., an appropriate query by the host will result in a data stream returned from the system as defined below.
Page 27
FC Series w/ EDC Control Thermal MNL-047-A Division Rev. 004 Examples: "START" Wake up system "STOP" Shut down system "POLL" Force a response from the system 2) Parametric Command A parametric command describes a function/command for which a value must be specified. The command characters must be followed by an "equals sign"...
Page 28
FC Series w/ EDC Control Thermal MNL-047-A Division Rev. 004 TRANSMITTED DATA It is anticipated that in a remote-controlled operation of the target system, the actual controlling "device" may be either a computer with a software program, or a human being working interactively. The format of returned data has been optimized for evaluation by a computer program, although it can be intelligently read by a human working in an interactive mode.

FC Series w/ EDC Control Thermal MNL-047-A Division Rev. 004 TRANSMITTED DATA FORMAT Acknowledge The explicit characters "OK" acknowledge receipt of a valid message, followed by 11 spaces (not counting the space for line continuation, described below). Error The line begins with the character "E", followed by a 3-digit decimal value defining the error number. It is up to the user to provide necessary messages defining the error, if desired.
Page 30
FC Series w/ EDC Control Thermal MNL-047-A Division Rev. 004 Example: Received string: Transmitted message: <CR> F057=-0030.00!<CR> (Function #57, Setpoint, is currently -30 degrees) Terminator The exclamation point ("!") is issued prior to the last <CR> to indicate "end of message", so that multiline messages may be accommodated.
