USING THE PCU TO ACTIVATE A GATE CONTROLLER
You can use a relay position in the CFN Mechanical PCU to activate a gate controller. This is only
available as a Fuel Point transaction, not via card, console, POS terminal, or terminal command.
1. The CFN PCU can directly switch power to a gate controller. The maximum rating of the PCU
relay is 3/4HP @ 120VAC. If your gate controller uses a different control voltage or exceeds
the 3/4HP rating, use an auxiliary mechanical relay with a 120 VAC coil to handle the load.
2. Up to 4 gate controllers can be accessed per PCU. You can also combine pumps and gates
within the same PCU.
3. Once the relay is closed, it will remain closed until one pulse is received on the PULSER input,
or until the switch timeout is reached, or the Fuel Point rings are separated, whichever comes
first. If the transaction ends by the pulse, the transaction is stored in memory. If the
transaction ends by timeout or ring separation, a message is logged but nothing is stored in
memory.
4. The PULSER signal can come from a dry-contact switch with no other voltage or circuits
connected, or it can be a 12VDC signal. Be sure to set the appropriate pulser input jumper as
shown. The jumpers are K1 through K4 and correspond to gates 1 through 4, respectively.
5. Receipts are not available for these transactions.
