9.2 Simulation
Simulation can be used to check the FMC 671 Z/676 Z and external downstream devices.
Four modes are possible:
• Simulation of frequency, V9H6
• Simulation of level, V9H7
• Simulation of volume, V9H8
• Simulation of current, V9H9.
When a value is entered at the appropriate matrix, the analog outputs are fed with the
appropriate current and voltage.
ActivationEnter operating mode 6 for channel 1 or 7 for channel 2 in V8H0; the red alarm LED
flashes during the simulation.
Step Matrix Entry Significance
1 V8H0 e.g. 6 Operating mode 6, simulation channel 1
2 - »E« Registers entry
Frequency simulation
Step Matrix Entry Significance
1 V9H6 e.g. 100 Depending upon the calibration and linearization, a value
corresponding to 100 Hz is displayed
