4.7 Power Monitoring Module
4.7.1 Functions of the Power Monitoring Module
The Power Monitoring Module is shown in Figure 11. The Power Monitoring Module is a
standard part of the Vortex system.
Note: for multiple Vortex Rack, Vortex panel and Vortex DIN systems supplied by Crowcon,
the Power Monitoring Module may have been replaced by a single Power Management
System, which meets the EMC and Low Voltage Directive requirements.
If the backup batteries are fitted and the main ac power supply is lost, the system
automatically switches over to the standby battery operation. If loss of power continues, the
battery is disconnected from the system to prevent it from being over-discharged and
permanently damaged.
The main features of the Power Monitoring Module are listed in Table 16.
