Replacing the PIN Pad
Tools Required: 3mm Allen key (hex key).
In the unfortunate event the Pin Pad module
needs to be replaced, follow these steps to
complete the swap and resume normal
operations:
1.
Open the TT8900 OPT door using the
commissioned key.
2.
First power off the UPS battery then,
disconnect the TT8900 OPT unit from
the mains power.
3.
Disconnect the five cables [ETHN,
COM1, COM3, POWER, USB] from the
PIN Pad and tie clear of unit.
4.
Unscrew by hand the two bolts and
remove the bracket holding the PIN
Pad to the front fascia plate.
5.
Withdraw the PIN Pad (lift each side
to break gasket seal).
6.
Ensure the sealing gasket is positioned correctly over the mounting studs.
7.
Install the new PIN Pad into position.
8.
Secure the PIN Pad with original retaining nuts. Give each mounting spacer an extra
half-turn so the gasket seals correctly, tightening evenly across the unit (ie: left
bottom, then right top, then left bottom etc.)
9.
Undo STEP 3, 4.
10.
Power up the unit:
the battery, then
the mains power.
11.
Close the OPT door.
12.
Wait for the “INSERT and REMOVE CARD” prompt on
the screen.
13.
To complete the installation, please finish the pairing process.
Note: Pairing is the process of exchanging security keys between the PIN Pad and the reader
to ensure only a “trusted” reader can pass card details to the PIN
Pad for processing.
The pairing process is done remotely by Transponder Technologies. To arrange for this to be
done, please contact TT Fuel Customer Support at:
