Activating 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 and is not using a card, console, POS terminal, or
terminal command.

Notes:1) The CFN PCU can directly switch power to a gate controller. The maximum rating
of the PCU relay is 3/4 HP @ 120 VAC. If your gate controller uses a different
control voltage or exceeds the 3/4 HP rating, use an auxiliary mechanical relay with
a 120 VAC coil to handle the load.
2) Up to four 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. However, nothing is stored in the memory.
4) The pulser signal can come from a dry-contact switch with no other voltage or
circuits connected, or it can be a 12 VDC signal. Ensure that you 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.
