Testing the Overfill Alarm on the GREEN MACHINE VST Control Panel
6.7.1
TLS-350 Overfill Alarm Test
•
This procedure will test the connection from the TLS-350 to the VST Control Panel.
•
The VST Control Panel may or may not be wired/connected to the TLS-350 Overfill Alarm
relay as outlined Chapter 3: Electrical Installation.
•
When an Overfill occurs, the Overfill relay closes which completes a 24 VDC circuit to the VST
Control Panel. The GREEN MACHINE will remain OFF two hours after the Overfill Alarm
clears.
Procedures:
1. At the TLS-350, Press MODE until the screen reads SETUP MODE.
2. Press FUNCTION until the screen reads OUTPUT RELAY SETUP.
3. Press the PRINT button to print a list of output relays, then read the printout and
identify the relay number associated with the OVERFILL for the GREEN MACHINE.
4.
Figure 6-11
shows the GREEN MACHINE OVERFILL relay as relay number 2.
5. Press MODE to return to ALL FUNCTIONS NORMAL screen.
6. At the ALL FUNCTIONS NORMAL screen, press FUNCTION until the screen reads TEST
OUTPUT RELAYS.
7. Press the STEP button until the screen reads TEST OUTPUT RELAYS ENTER RELAY
NUMBER 0.
8. Press the number on the keypad that corresponds to the relay assigned to the GREEN
MACHINE output relay, then push ENTER.
9. The screen should read R X: GM OVERFILL PUSH ALARM/TEST KEY.
10. Press RED ALARM/TEST button to activate the GREEN MACHINE Overfill relay.
11. If the Overfill Alarm is active, the wiring of the Overfill Relay and the Overfill
programming is correct. After two hours, the Overfill Alarm will clear.
12. If the Overfill Alarm is NOT active, contact the General Contractor or the electrical
contractor to correct the wiring from the VST Control Panel to the TLS-350 Overfill
relay, then conduct the test again until the test passes and the Overfill Alarm is active
on the VST Control Panel PLC.
13. After the test is concluded, press the MODE button at the TLS-350 until the screen
reads ALL FUNCTIONS NORMAL.
14. The Test has passed and is concluded. The GREEN MACHINE will remain OFF for two
hours after the test is completed.
