TankGate Interface

Installation and Operations Manual

The recommended standard housing for the TankGate is a NEMA TYPE 4 enclosure. This 

enclosure is suitable for both indoor and outdoor applications.

Switch SW1 sets the TankGate’s one byte, binary address (0-15). Switch SW1-1 is the 

most significant bit (MSB) while switch SW1-4 is the least significant bit (LSB). When a 

switch is in the ON or CLOSED position, the resulting bit is a one.

The TankGate operates from AC power. 

Wiring 120 or 220 VAC Power

The TankGate is powered by an isolation transformer with a 5 volt regulator.

• 

Remove cover if it is in place

• 

Connect the two power leads to terminals L and N of connector J2. 

• 

Ensure that a ground connection is connected to the G terminal ground of 

connector J2. (see below)

• 

Install cover.

To allow use in harsh industrial environments, the TankGate incorporates ANSI/IEEE 

surge protection. In solid-state control systems, grounding helps limit the effects of 

noise due to electromagnetic interference (EMI) and provides additional surge protection 

when high voltage switching circuits are connected to the unit. The grounding path for 

the TankGate and its enclosure is provided by the equipment grounding connector. The 

resistance from the TankGate ground to the grounding electrode must not exceed 1 

ohm. Additional ground wires should be connected as required for each I/O module.

All applicable codes and ordinances must be observed when wiring the TankGate.

RS-232 Communications

• 

To install the RS-232 communication option, connect an RS-232 cable to 

connector J7 (COM0) or J5 (COM1).

When using COM1, Switch SW2 must be set for RS-232 mode.
