The “Setpoint menu” is used to set the setpoints for the various available functions. The “I/O menu” shows the status of the digital inputs and values read from the analogue inputs. It also shows the status of the digital outputs and the voltage supplied to the analogue outputs.

  • Page 14: Configuring The Terminals

    The first operation to perform when a network is started up for the first time or a card is replaced, is to perform the procedure for terminal configuration. This cannot be achieved with the basic W3000 keypad. In this case, configure the terminals using the W3000 or W3000 compact keypad and then connect the W3000 basic display.
  • Page 15 C0240111-01-06-GB 3.4.2 SETTING CARD ADDRESSES The card address is set by the software using the keypad. Proceed as follows: Make sure the keypad address is set to 0 ( see para 3.4.1). Display address Setting..:00 I/O Card address: Disconnect the card from the power supply (turn off the general switch).
  • Page 16 To connect several units together and remote control them, thereby forming a plan network (global), a remote keypad controlling all the units is required. The remote keypad cannot be used with a W3000 basic keypad. If a W3000 basic keypad is installed on the machine, replace it with a 3000 compact.
  • Page 17 In this case, the various machines of the network are switched by pressing [ESC] and [UP] together. If the plan network does not comprise just W3000 chillers, a 16-key keypad must be used. In this case, press [UNIT] to switch between one card and another. In this case, however, the terminals must be given a special configuration as the 16-key keypad is only recognised on “terminal 3”.
  • Page 18 C0240111-01-06-GB CONNECTING THE REMOTE KEYPAD: “T” SHUNT: Let us analyse a vital component for connecting several units in a network: the “T” shunt. This is a shunt with phone connectors (called A,B,C in figure 3.4b). CONFIGURATION: For our purposes, configure terminals J14 and J15 (see Figure 3.4b).
