The example on Figure 3 shows the switches 1, 2 and 4 on the ON position. So the corresponding values are 1, 2 and 8, giving an address sum of 11. (1+2+8=11) The ProLon network allows a maximum of 127 addresses, therefore 127 controllers. Figure 3 - Addressing Dipswitches...
The C1000 Water Loop Controller has 2 separate communication ports offering the same functionality on each. Both act as ports for incoming Modbus communications from other ProLon devices or interfaces, such as a Network Controller or remote computer with ProLon Focus software.
Inputs Temperature Sensors The C1000 Water Loop controller has an analog inputs dedicated to monitoring the supply and return water temperatures and will integrate these reading into its control sequence. An auxiliary temperature sensor input in also available (for visualisation purposes only) and will not affect the sequence. The sensors used are standard 10k type 3 thermistors.
Outputs The C1000 Water Loop controller contains 5 configurable outputs. The first 4 outputs are ON-OFF triac outputs. Output 5 is an analog 0-10VDC ON-OFF or modulating output, fully customizable via the ProLon Focus software. An integrated resettable fuse protects each of the outputs of the C1000 against current surges and short circuits.
2) Switch position to obtain a SINK passive output (see Figure 9): Switch for Output 4 Isolated dry contact (On/O ) Figure 9 - Output in SINK mode Typical Connection of Digital Outputs 1 to 4 Two types of configurations are possible: 1) Active output (SOURCE).
Typical Connection of Analog Output Two types of configuration are possible: 1) The C1000 powers the load and provides a control signal (see Figure 12). 24 VAC power (From terminal block #2 of the controller) Controlled 0-10v 0-10v Load Figure 12 - Connecting the Analog Output (Controller Powered) 2) The C1000 only provides the control signal to the load, which is powered by an external source (see Figure 13).
Power Source / Network Power Source The ProLon C1000 controller is powered by a 24 VAC power source connected using the "COM" terminal and the "24 VAC" terminal (see Figure 14). The common for all inputs and outputs are the same as the power source’s common (exception: when an output is set to passive, the common for this output will not...
