CAREL in this case, through specific agreements, can intervene as consultant for the positive result of the final start-up machine/application, but in no case can it be held responsible for the positive working of the final equipment/apparatus.

Page 7: Introduction
INTRODUCTION General description μC SE for process chiller is a compact electronic controller designed for the complete management of the process chiller with 1 refrigerating circuit: it can control air-water and water-water machines. The controller has 5 digital inputs, 5 digital outputs, 4 analogue inputs and 1 analogue output. It can be installed: individually;... - Page 8 (MCH200TW00). For further information see the instruction sheet +050001065. Programming key (code PSOPZKEY*0) The programming keys PSOPZKEY00 and PSOPZKEYA0 for CAREL controllers allow the copying of the complete set of parameters of the μC SE. The keys must be connected to the connector (AMP 4 pin) envisioned in the controllers and can operate with controllers powered or not.

The protection against short circuits due to faulty wiring must be guaranteed by the manufacturer of the appliance that the controller will be fitted on. Programming key (copy of the set-up) The PSOPZKEY00 and PSOPZKEYA0 programming keys for CAREL controllers allow to copy the complete set of μC SE parameters. The keys must be connected to the connector (AMP 4 pin) envisioned in the controllers and can operate with instruments that are live or not, according to that indicated in the user notes of the specific controller. - Page 13 The operation is completed in 10 seconds. If the completed signal with green LED on is not given within this time period, it is good practice to attempt the operation again, releasing and pressing the button again.

Page 14: User Interface
USER INTERFACE The front panel contains the display and keyboard, made up from 4 keys, which, pressed individually or together, allow to perform all of the controller programming operations. Display The display features 3 digits, with the display of the decimal point between -99.9 and 99.9. Outside of this range of measurement, the value is automatically displayed without the decimal (even if internally the unit still operates considering the decimal part). -

Page 17: Minimum And Maximum Fan Speed Calculation
Other configuration parameters (par. c14, /23, H09, P35) c14 establishes the number of operating hours of the compressors/pumps, expressed in hundreds of hours, over which to activate the maintenance request signal (Hc1, Hc2). c10 and c11 are read only parameters and indicate the number of operating hours of the compressors 1 and 2, expressed in hundreds of hours. -
Page 18: Functions
FUNCTIONS 5.1 Set point The control algorithm is the ON/OFF type according to the figure. The set point r01 can be set from a minimum value to a maximum value (par. r13, r14). The probe selected for the control depends on parameter r06, once enabled with the parameters /01 and /02. If r06 = 0,1 the probe is B1. If r06 = 2, 3, 4 the control probe is B2. -
Page 19: Probe Reading
The probes B1/B2 have the function of input/output evaporator temperature. The probe B3 can be configured as condensation temperature probe, external or differential control. The external probe allows the activation of the external compensation algorithm. The probe B4 can have the same functions as B3 and in addition acts as digital input (can be configured from par. -

Page 21: Analogue Outputs
Analogue outputs The analogue output Y1 is set-up for the condenser fan and is active if F01 = 1. In systems with hot gas bypass function enabled, the bypass valve is commanded by the output Y1 (controller) or Y2 (I/O expansion board). See the control chapter. 5.7 Compensation The compensation can indifferently increase or decrease the value of r01 depending on whether r17 is respectively positive or negative. -
Page 22: Control
CONTROL Anti-freeze The anti-freeze probe is B2. The anti-freeze set-point A01 represents the temperature below which the machine passes to anti-freeze mode: alarm A1 activates and switches the alarm output. The value of A01 is limited by A07. A03 is the intervention delay time of the anti-freeze alarm when starting the machine. - Page 23 Protection for outputs with different relays (par. c04, c05) c04 establishes the minimum time that must pass between successive switch-ons of 2 compressors. By delaying the connection, line overloads are prevented due to close or simultaneous peaks, c05 establishes the minimum time that must pass between the switch-off of the two compressors. Par.

Page 26: Fan Management
6.7 Fan management Fan operation F01 enables the condenser fan output, according to the output assigned by parameter H11. Depending on the type of fan, the controller PWM output (Y1), always active, requests the presence of optional boards: 1) CONVONOFF0 for the conversion of the PWM output into ON/OFF output; 2) CONV0/10A0 for the conversion of the PWM output into 0…10 Vdc or 4…20 mA output;... -
