4 ELECTRICAL INSTALLATION Warnings. • To comply with Underwriter Laboratories (UL) and Canadian Standards Association (CSA) certification, route signal leads and power cables in earthed (grounded), flexible metal conduit. Use the Position 1 protective ground stud (NOT the terminal module ground stud) to ground the flexible metal conduit. •...
4 ELECTRICAL INSTALLATION… 4.1 Identifying the Input/Output Modules – Fig. 4.2 To gain access to the modules, open the door and chassis – see Fig. 2.2. There are six module positions as shown in Fig. 4.2. 4.2 Channel Connections are made directly to the terminal block Channel 1 connections mounted on the motherboard.
…4 ELECTRICAL INSTALLATION 4.2.1 Selecting the Analog Input Type(s) – Figs. 4.3 and 4.4 Plug-in links are used to select the input type: PL1 & PL8 on the main p.c.b. (Fig. 4.3) Channel 1 PL1 & PL3 on the module (Fig. 4.4) Channels 2 to 4 DJ4 IC19 C 119...
4 ELECTRICAL INSTALLATION… 4.2.2 Voltage and Current – Fig. 4.5 4.2.5 Resistance Thermometer (RTD) – Fig. 4.5 Input impedances: If long leads are necessary it is preferable to use a 3-lead Low voltage (mV) >10MΩ resistance thermometer. Voltage >10MΩ If 2-lead resistance thermometers are used each input must be Current (mA) 100Ω...
…4 ELECTRICAL INSTALLATION 4.2.9 Motorized Valve – Fig. 4.6 A motorized valve with or without feedback requires 2 relays (common and normally open terminals) to drive the valve in either direction. Any two relays can be allocated for this function. Fig. 4.6 A shows two possible combinations. Note.
