For testing, communication links to external devices via Modbus/TCP output, such as a
PLC connection, the ACM 150 monitor, and higher features Alarm Simulation.
When simulating an alarm on a specific port and for one or more gases, a message
assuming an Alarm Level + 5% concentration for each selected gas is sent via
Modbus/TCP.
For each selected gas, the simulated alarm event is displayed on the Alarms screen of the
ACM 150 user interface. Simulated alarms are auto-cleared and do not trigger the red
Alarm icon on the title bar.
1. Select the point you want to simulate gas alarms.
2. Select the gases for simulating alarms.
3. Press "START" to start simulating.
4. Alarm simulation is running only on this screen. Press "QUIT" to stop the simulation.
