Hook / Turbine outputs cannot drive the pump directly. The turbine output should be wired to
the tank gauge’s Auth input or the turbine contactor coil. If the site has dispenser sump sensors
or submersible sump sensors the VMI controller is not monitoring, the VMI turbine outputs
should become the tank monitor’s authorizations. In this manner, the pump starting and
stopping is subject to the site sensors. Alternatively, Sump Alarms and E-stop can be wired to
break main power to the ISM.
B-2. AC Outputs: Non-Control Valve Applications
1. (8) 120VAC Outputs
(4) Hook / Turbine Outputs
(4) Alarm Outputs
2. All outputs provide a switched hot.
3. Each output can supply no more than 2 amperes of current.

power to the ISM.
C. Alarm Outputs:
1. Alarm outputs are provided per product or turbine. Alarm Outputs are dynamic depending upon
site configuration. Alarm Outputs can be wired to ATG alarm inputs, separate annunciators, or
building management systems.
D. AC Inputs:
1. Up to four 120 VAC Authorization inputs (require a switched hot).
Typically, one input per product. Different options are available per site configuration.
2. Each AC input draws only 20 mA.
E. Low Voltage Inputs/Outputs (5 VDC):
1. Must enter enclosure in the Intrinsically Safe area – bottom of the enclosure on the right side.
2. Low voltage intrinsically safe wiring only connects to the terminal blocks in the area on the
bottom right side of the enclosure labeled left to right 1 – 4.
3. All low voltage wiring should be twisted pair 14 – 22 AWG with shield.
4. Each piston switch pair connects to a single terminal block.
5. Shield should be connected to the provided terminal
blocks grouped with each IS switch
. Ground
(shield) should not be connected in the sump.
