Page 4: Functional Specification
The MC2-FC uses 2-conductor Pt1000 sensors instead of 3-conductor Pt100 sensors. · The MC2-FC cannot be operated with the Alfanet PC program. Instead, the VDH Alfa Server Program (VASP) is now available. That program can be used to operate both the MC2-FC controllers and the FC785-PC controllers (from software version 2.10). -
Page 5: Commissioning
MC2-FC mode FC Document no.:200064 Version: 1.5 The controller has 5 temperature sensor inputs (which can also be used as digital inputs) and 5 relays. If more inputs or relays are necessary, the controller can be expanded with an optional 907.100054 MC3-EM [1Do12,1Rth16] extension module. -
Page 6: Phases And Cooling
MC2-FC mode FC Document no.:200064 Version: 1.5 1.3 Phases and cooling The controller functions in 3 phases. These phases mainly relate to the control of the mechanical cooling (fluid valve and a suction valve, where relevant). Cool phase: In this phase, the cell starts mechanically cooling when the control temperature exceeds the temperature set point + temperature differential. -
Page 7: Defrost
MC2-FC mode FC Document no.:200064 Version: 1.5 1.5 Defrost The controller supports 3 defrost methods, which are described in detail below. A defrost action can be started manually or on the basis of clock time intervals or real-time intervals (P810..P843). A defrost action only starts when the defrosting temperature is lower than the defrost release temperature (P850). -
Page 8: Ventilation Functions
MC2-FC mode FC Document no.:200064 Version: 1.5 1.6 Ventilation functions The controller supports 2 separate ventilation functions: Cooling ventilation: This ventilation function is linked to an evaporator and used during cooling and off-cycle defrosting. The function can be switched on and off automatically, but can also be continuously switched on manually. -
Page 9: Day/Night Mode
MC2-FC mode FC Document no.:200064 Version: 1.5 1.9 Day/night mode The day/night mode is used to determine the temperature set points. The mode is automatically switched on using parameters (P350..P351). 1.10 Set point link The temperature set point can be linked to another cell (P805]. The controller then uses the same temperature set point as the cell to which it is linked. -
Page 10: Sensor Offsets
MC2-FC mode FC Document no.:200064 Version: 1.5 1.14 Sensor offsets The controller has a sensor offset parameter for every sensor (P200..P216). It can be used to correct the indication by the inaccuracy of the sensor and (partly) the measurement circuit of the controller. -
