TECHNICAL SPECIFICATIONS - Power supply: TC-900Ri power: 115 or 230Vac ±10%( 50/60 Hz) TC-900RiL power: 12 or 24 Vac/dc - Control temperature: -50 to 75° C / -58 to 167°F - Operating temperature: 0 to 40°C / 32 to 104°F - Operating humidity: 10 to 90% RH (without condensation) - Resolution: 0.1°C from -10 to 75°C and 1°C outside this range /1°F in all range - Load current (outputs): COMP: 12(8)A/240Vac 1HP (compressor, solenoid valve or contactor) DEFR: 10A / 240Vac 1/4HP (defrost resistance or hot gas) FANS: 5(3)A / 240Vac 1/8HP (evaporator fans) - Dimensions: 71 x 28 x 71mm - Sensors: S1: ambient sensor (black cable) S2: evaporator sensor (gray cable) . For cooling and defrosting, works with two sensors, one being for ambient temperatura and the other fixed to the evaporador that controls defrost ending. With the powerful 16-amp relay, directly controls compressors up to 1 HP. The defrost output has a 10A current capacity, as well as also having Normally Closed (NC) contact avaiable. It also has indicators in ºC and °F and digital filters, which have the purpose of simulating an increase in mass in the environment sensor (S1), thus increasing its response time (thermal inertia) and preventing unnecessary activations of the compressor. Product complies with UL Inc. (United States and Canada) and NSF (United States). 4.2 - Parameters table Description Fun Access code:123 (one hundred and twenty-three) Control differential (hysteresis) Offset indication for ambient sensor Minimum setpoint allowed to the end user Maximum setpoint allowed to the end user Delay when the instrument is powered on Act point of high ambient temperature alert Refrigeration time (interval between defrosts) Compressor delay after on (on - off) Compressor delay after off (off - on) Compressor status with detached ambient sensor (S1) Defrost when the instrument is powered on Evaporator temperature (S2) for end defrost Maximum duration of defrost (for security) Fan turned on during defrost Defrost type Min Max Unit Standard CELSIUS FAHRENHEIT - 0.1 -20.0 -50.0 -50.0 0 -50.0 1 0 0 0 - off 0 - no -50.0 0=disable 0 - no 0 - electric - 1 -36 -58 -58 0 -58 1 0 0 0 - off 0 - no -58 0=disable 0 - no 0 - electric - 20.0 20.0 75.0 75.0 30 75.0 999 999 999 1 - on 1 - yes 75.0 90 1 - yes 1 - hot gas - 36 36 167 167 30 167 999 999 999 1 - on 1 - yes 167 90 1 - yes 1 - hot gas - º C º C º C º C min. º C min. sec. sec. - - º C min. - - - 1.5 0 -50.0 75.0 0 40.0 240 0 0 1 - on 0 -no 40.0 45 0 0 - °F °F °F °F min. °F min. sec. sec. - - °F min. - - - 3 0 -58 167 0 104 240 0 0 1 - on 0 -no 104 45 0 0 Min Max Unit Standard 4.3 - Parameters description F01 - Access code (123) To change the parameters it is necessary to use the access code.It is not necessary to use the access code to visualize the adjusted parameters. F02 - Control differential (hysteresis) It is the difference of temperature (hysteresis) between to turn OFF and turn ON the refrigeration output. Example: To control the temperature in 4.0°C with differential of 1.0°C. Soon, the refrigeration will be turned off in 4.0°C and turned on again in 5.0°C (4.0 + 1.0) F03 - Offset indication for ambient sensor It allows to compensate eventual shunting lines in the reading of ambient temperature (S1) proceeding from the exchange of the sensor or cable length alteration. F04 - Minimum setpoint allowed to the end user F05 - Maximum setpoint allowed to the end user Electronic limits whose purpose is to prevent that too high or too low setpoint temperatures are regulated. F10 - Compressor delay after off (off-on) It is the minimum time that compressor will keep off, it means, space of time between the last stop and the next drive. It serves to alliviate the discharge pressure and to increase the time of useful life of the compressor. F11 - Compressor status with detached ambient sensor (S1) If the ambient sensor (S1) will be damaged or outside the specified range, the compressor assumes the configured status in this function. Example: For counters of fruits, it is better to keep the compressor off. In counters of meat it is better to keep the compressor on. F12 - Defrost when the instrument is powered on It makes possible the accomplishment of a defrost at the moment that controller is energized, for example, in the return of electrical energy (in case of energy lack) F13 - Evaporator temperature (S2) for end defrost If the temperature in the evaporator (sensor S2) reaches the adjusted value, the end of defrost will be for temperature. With this, the defrost process is optimized. F06 - Delay when the instrument is powered on When the instrument is powered on, its control is kept disabled during a time, delaying the start of process. During this time, it works only as temperature indicator. It serves to prevent demand of electric energy peaks, in case of lack or return of the same and when exists a lot of equipment connected on the same net. For this, just adjust different times for each equipment. This delay may be of compressor or defrost (when exist defrost on turn on). F07 - Act point of high ambient temperature alert If the ambient temperature (sensor S1) reaches this point during refrigeration, this will be signaled visually through the indication blinking on display. F08 - Refrigeration time (interval between defrosts) It is the time which compressor will turn on and turn off only for ambient temperature and starts to be counted when the fan is turned on , after fan-delay stage (fan return after draining). F09 - Compressor delay after on (on-off) It is the minimum time that compressor will keep on, it means, space of time between the last drive and the next stop. It serves to prevent high voltage events in the electric network.
