APPENDIX (continued) Step Eight
Simulation (SIM‐T): This mode enables the end user to simulate changes in level without having the level of
liquid move. The display will simulate level of liquid and will turn the relays ON and OFF according to how they
were configured. Example: If Relay 1 is set as a High Alarm with an ON setting for 100.0 inches and a Hysteresis
of 2.0 inches, then when the display goes above 100.0, Relay 1 will energize and when the level falls below 98.0,
Relay 1 will de‐energize. Use this function to test the wiring and to verify the sensor’s configuration.
Please note: Simulation mode will energize and de‐energize all configured relays. Any devices wired to the
relays will become active during simulation mode.
1. In TOP‐LEVEL MENU, select HELP.
2. Select SIM‐T.
3. The display will start at 0.0.
a. Press and hold the UP button to begin
increasing the level of liquid.
b. Use the DOWN button to simulate the
lowering of liquid in the tank.
c. To increase speed, hold the SELECT button
while hold the UP or DOWN keys.
4. Test the functionality of the relays confirming
their ON and OFF levels.
5. To exit, press and hold the SELECT key.
6. Select EXIT to return to TOP‐LEVEL MENU.
Test Parameters: This mode runs diagnostic tests that confirm operation of EchoSwitch®. This is a production
test feature used by the factory to confirm operation.
1. In TOP‐LEVEL MENU, select HELP.
2. Select TEST P.
3. TEST P will perform the following test:
a. Run a LCD Check
b. Turn ON all three relays
c. Turn OFF all three relays.
4. TEST P will also list the following settings:
5. Select EXIT to return to TOP‐LEVEL MENU.
Note: This mode should only be used when
supervised by a Flowline representative.
