Automatic Transfer Switches are often used in critical applications. Failure of an Automatic Transfer Switch to operate properly could cause property damage, personal injury or death. Extreme caution must be used when designing or using programming software that will communicate with the Automatic Transfer Switch. Improper use of the Modbus network variables will cause the Automatic Transfer Switch to malfunction. Always conduct a full test and debug of the programming software prior to installing and using it in the system. |

The ZNET100 network card enables the communication of the following information: the position of the transfer switch, the sources that are available, the timers that are running and the test that is running. The information is sent to a remote annunciator panel, a PC, or a PLC via one pair of twisted wires. The wires should be 16 AWG. This cable is not included. The connections are located below the relay for the engine start timer.
