ABB PM891K01 Channel intelligent module

The introduction of RS-422 communication capabilities, made possible the concept of a bussed system of generators being controlled from one central control point. See Figure 2.5.2 below for the RS-422 System Diagram. Each generator is assigned an address and control of that address is achieved via the identity (IDE) command. The IDE ncommand selects an address corresponding to the n value, which is a hex number from 0 - FFH. When the command is asserted the corresponding device at that address is the only device on the bus and all other devices tri-state their transmitters. The IDE address of a generator is configurable within the CAL8 menu. The link release [!!]is another command used in the realization of the RS-422 Bus Architecture This command will remove all devices from the bus and put all devices into listen mode. This command is only active until the next IDE ncommand which will enable one of the still listening devices to active its transmitter.  

MATCHWORK® Interconnection 

The following diagrams shows the typical interconnection of a GHW-25 / GHW-50 Genesis generator using ENI’s DSP-based matching networks with an optional MW local control and a generator front panel MW control. The interconnect consists of three types of cabling: AC power, RF power and control.

The DSP-based matching networks consume about 100W of power while tuning and about 50W in "idle" mode (both capacitors stationary). They use one metric glass fuse (5 x 20mm). The recommended fuse rating is 4A.

MATCHWORK® Power Requirements 

The matching networks can operate from a range of AC input voltages at either 50 or 60Hz. AC voltage input may be any voltage in the range from 90 V to 264 V. No setups or adjustments such as transformer tap changes are necessary. AC power and ground are brought to the unit via the IEC connector labeled AC INPUT. AC Mains is supplied directly to the matching network. A separate AC mains supply is required for the RFC-6 remote controller, which has a voltage selector on the rear panel. Each unit uses standard IEC connectors for power input.
