Valves
There are eight high current outputs on the Superflex 4 designed to drive four dual coil (bi-directional)
valves. Each output is rated at 3 amps maximum, and has built in short circuit protection. Figure 9 depicts
a typical connection. This example shows the channel 1 valve’s two coils connected to BT3 terminals 12
and 6 for the “A” and “B” directions. In general -
"
An output from Superflex connector BT3 is connected to the plus side of the valve.
"
The minus side of the valve is connected to the machines ground or battery minus terminal.
There are two AUX (auxiliary) high current outputs on BT3. Depending on the Superflex 4 application,
these outputs may control the machine’s dump valve, throttle, etc. The AUX outputs are connected in a
similar fashion as the valves shown above.
Superflex 4 Controller
The Superflex 4 has three 12 pin connectors: BT2 is used for inputs, BT3 for outputs and BT1 for power
and Optimizer connections (see figure 10 on the next page for the connector locations). Cables and / or
wiring harnesses may be purchased from OEM Controls in any desired length. Appendix 4 shows the
terminal pin numbers and wiring for your particular application. The BT pin numbers are idendified in
figure 11 on the next page.
Revision B and later Superflex 4 Controllers have two additional 4 pin connectors, BT4 and BT5.
Connector BT5 has power and ground connections, and BT4 has Optimizer connections. Either BT1, or
both BT4 and BT5 may be used for your application.
A label on the Superflex 4 Controller also identifies all connector pins and their functions.
