Endress+Hauser prolevel FMC 661 - Simulated Operating Mode

6.3 Simulated operating mode
This function is intended primarily for checking the correct function of the system:
• Enter 6 at V8H0 to activate the simulation mode for level measurement
• Enter 7 at V8H0 to activate the simulation mode for level switching
• Enter 0 at V8H0 to terminate simulation and resume normal measurements.
When the simulation mode is activated, the alarm relay flashes (Warning E613 or E614).
The following simulations are possible:
Matrix Entry Simulated variable
V9H6 (V8H0 = 7) 0 = switch uncovered
100 = switch covered
External limit switch
for Liquiphant values reversed
V9H7 (V8H0 = 6) Level Level, current, volume
V9H8 (V8H0 = 6) Volume Volume, current
V9H9 (V8H0 = 6) Current Current
The level simulation mode takes the last measured value as default value in V9H7.
Example:
Simulation of volume
and current by entry of
level in V9H7
# Matrix Entry Significance
1 V8H0 6 Select simulation
2 - »E« Register entry
3 V9H7 e.g. 80% Enter level
4 - »E« Register entry
5 V9H8 **.** Volume for level
6 V9H9 **.** Current for level
7 V8H0 e.g. 1 Measurement mode
8 - »E« Register entry
Example:
Simulation of current by
entry of volume in V9H8
# Matrix Entry Significance
1 V8H0 6 Select simulation
2 - »E« Register entry
3 V9H8 e.g. 500 Volume = 500 hl
4 V9H9 **.** Current for volume
5 V8H0 e.g. 1 Measurement mode
6 - »E« Register entry
Example:
Simulation of covered
external limit switch
# Matrix Entry Significance
1 V8H0 7 Select simulation
2 - »E« Register entry
3 V9H6 100 Switch covered
4 V8H0 e.g. 0 Measurement mode
