Connection Alternatives The field equipment power supply can be connected in the same manner as that used for connecting and powering the AC 800M units (see Figure 61 on page 177 and Figure 62 on page 178). However, it should be noted that the same Mains Breaker Unit can be used to control and isolate both power supplies. Alternatively, independent Mains Breakers can be used on each spur (see Figure 62 on page 178)

The AC 800M Controller can be powered from an external +24 V DC source. This source is often common for many different types of plant equipment, resulting in long power cables to the AC 800M Controller. Furthermore, heavy load changes can cause variations in controller supply voltage making it necessary to take precautions against low voltage in order to prevent controller malfunction. Should there be a risk that the +24 V at the PM8XX power terminals could drop below 19.2 V for more than 1 ms, then an energy reservoir must be used for Powering Units. ABB requires the use of DC/DC converter and extra energy reservoir in case external DC-supply with longer cables than 10 m is used. For redundant power supplies to the AC 800M controller and associated units, always derive connections from the SS8xx voting device. See Figure 61 on page 177.

This section describes the operation of the AC 800M Controller, comprising a PM8xx (single or redundant configuration) processor unit, together with various optional units. For additional technical information on optional units, see Appendix A, Hardware Units. AC 800M Controller (PM8xx) Equipped with Control Software, the basic PM8xx/TP830 or PM891 hardware units mounted on the AC 800M hardware platform constitute an AC 800M Controller.Normal state – ON Lit when internal or external battery voltage is above 3.1 V. The LED is controlled by a software battery voltage test(1).
