Figure 3-6:
Shows the Field Wiring from the VST Control Panel to the GREEN MACHINE Internal Junction
Box: Vacuum Pump Motor, Pressure Sensor, Safety Power Switch
1.
Wiring the Internal Junction Box
a.
Install 6 wires from the VST Control Panel to the junction box
a.
Vacuum Pump 115 VAC to wire number 02052
b.
Vacuum Pump Neutral to wire number 02042
c.
Control Valve V1 115 VAC to wire number 02062
d.
Control Valve V2 115 VAC to wire number 02072
e.
Control Valve V5 115 VAC to wire number 02074
f.
Ground to Ground
2.
Pressure Sensor Cable
a.
Install 1-Pressure Sensor Cable from the VST Control Panel to the Internal Junction Box
b.
The cable is supplied by the contractor
c.
The cable must be 3-conductor, 18 AWG, twisted and shielded
•
24 VDC (+) to wire number 02092
•
4-20 mA SIGNAL to wire number 04052
•

Wiring the Overfill Alarm Field Wiring
Figure 3-6:
Shows the Overfill Alarm Field Wiring from the VST Control Panel to the Fuel Management
System
1.
The VST Control Panel supplies 24 VDC to an overfill alarm relay.
2.
The overfill alarm output relay is a “dry” relay (N.O.) that shuts down the
GREEN MACHINE
when a UST reaches the Overfill Level volume during a fuel drop.
3.
Install two wires from the VST Control Panel to the Fuel Management System Overfill Alarm
(N.O.) output relay. (Refer to the Fuel Management System Installation Manual for
connecting and configurating the correct relay. Programming of the Overfill Relay will be
completed by other.)
a.
TLS-350 or equivalent Overfill Alarm Relay Circuit.
b.
Connect to the COMM Bay, 4-Relay Module
•
24 VDC (+) to wire number 02092
•
24 VDC (0) to wire number 04051
OR
c.
TLS-450 PLUS or equivalent Overfill Alarm Relay Circuit
d.
Connect to the Module Bay, I/O Module
•
24 VDC (+) to wire number 02092
•
24 VDC (0) to wire number 04051
