  • Page 4: Functional Specification

    The controller can be operated using the touchscreen. It can also be operated (also by remote control) using a computer on which the VDH Alfa Server Program (VASP) has been installed. VASP provides access to the advanced control functions such as registrations, alarm handling settings, etc.

  • Page 5: Commissioning

    MC2-FC mode MC Document no.:200063 Version: 1.3 1.2 Commissioning The following must be taken into account before the controller is commissioned: · When the Ethernet connection is used, the IP address must be checked/defined (see section 6.1). · The correct mode (FC or MC) must be selected (see section 6.2) ·...

  • Page 6: Heating

    MC2-FC mode MC Document no.:200063 Version: 1.3 Store phase: For the store phase, each cell is placed in a store group. Store groups can be formed by setting a store group number for each cell (P0320). Within each store group, each cell mechanically cools only once in a store cycle time interval until the control temperature reaches the temperature set point.

  • Page 7: Defrost

    MC2-FC mode MC Document no.:200063 Version: 1.3 1.5 Defrost The controller support 3 defrost methods, which are described in further detail below: A separate defrost group can be configured for each defrost method on the cell controllers (P0800..P0802). Different settings can be made for each defrost group (P2400..P2406 and other parameters), for example, the maximum number of cells that defrost at the same time, the number of cooling cells which are required for hotgas defrost.
  • Page 8 MC2-FC mode MC Document no.:200063 Version: 1.3 "Preference cells": These are cells that are identified as preference cell using parameter P0120. "Highest cool demand" cells: These are cells that are not cooling (yet), but that have a cool demand. These cells are forced to start cooling in sequence of decreasing cool demand.

  • Page 9: Ventilation Functions

    MC2-FC mode MC Document no.:200063 Version: 1.3 1.6 Ventilation functions The controller supports 3 separate ventilation functions: Cooling ventilation: This ventilation function is coupled to an evaporator and used during cooling and offcycle defrost. The function can be switch on and off automatically, but it can also be switched on continuously by manual control.

  • Page 10: Humidification

    MC2-FC mode MC Document no.:200063 Version: 1.3 1.7 Humidification The controller supports 3 humidification modes: Off: The humidification control is continuously disabled. Continuous: The humidification control is continuously active. Automatic: The humidification control is activated on the basis of the advanced automatic humidification timing settings that include pulse/pause timing and synchronisation with cooling and ventilation (P0600..P0631).

  • Page 11: Blocking

    MC2-FC mode MC Document no.:200063 Version: 1.3 1.11 Blocking If blocking is activated, all the control functions are stopped. Blocking can be activated during real- time periods (P1000..P1035) or with a digital input. If required, blocking can be ignored for automatic ventilation (P1040).

  • Page 12: Alarms

    MC2-FC mode MC Document no.:200063 Version: 1.3 1.15 Alarms The controller has 2 adjustable temperature alarms. Parameters (P0900..P0966) can be used to configure how the alarms operate: in which phase, on which sensor(s), against which reference, at which alarm delay and with which actions.

  • Page 13: Storage Cycle Order

    MC2-FC mode MC Document no.:200063 Version: 1.3 1.18 Storage cycle order In addition to the default store cycle order, the cell controllers also support the orders below. The order can be set per store group (P2202 and other parameters) "Rotating" order: This order is equal to the default order, however, the cell number which starts the cycle rotates: The first cycle starts, for example, with cell number 1, the second cycle with cell number 2 and so on.
