Chapter 2 Installation Dangerous voltages capable of causing death are sometimes present in this instrument. Before installation or beginning any troubleshooting procedures the power to all equipment must be switched off and isolated. Units suspected of being faulty must be disconnected and removed to a properly equipped workshop for testing and repair.
2 3 Wiring Precautions Before wiring, verify the label for correct model number and options. Switch off the power while checking. Care must be taken to ensure that maximum voltage rating specified on the label are not exceeded. It is recommended that power of these units to be protected by fuses or circuit breakers rated at the minimum value possible.
2 4 Power Wiring The controller is supplied to operate at 11-26 VAC / VDC or 90-264VAC.Check that the installation voltage corresponds with the power rating indicated on the product label before connecting power to the controller. Fuse 264 VAC or 26 VAC / VDC Figure 2.4 Power Supply Connections...
2 5 Sensor Installation Guidelines Proper sensor installation can eliminate many problems in a control system. The probe should be placed so that it can detect any temperature change with minimal thermal lag. In a process that requires fairly constant heat output, the probe should be placed closed to the heater.
2 6 Thermocouple Input Wiring Thermocouple input connections are shown in Figure 2.5. The correct type of thermocouple extension lead-wire or compensating cable must be used for the entire distance between the controller and the thermocouple, ensuring that the correct polarity is observed throughout.
2 7 RTD Input Wiring RTD connection are shown in Figure 2.6, with the compensating lead connected to terminal 12. For two-wire RTD inputs, terminals 12 and 13 should be linked. The three-wire RTD offers the capability of lead resistance compensation provided that the three leads should be of same gauge and equal length.
