THUNDER ELECTRIC TARP SYSTEM
OPERATING INSTRUCTIONS - Powering Up or Down the System
To turn the system on or off, locate the “OPEN” and “CLOSE” buttons on the relay module on the
front of the trailer. Push and hold both buttons simultaneously for approximately 3 – 5 seconds.
The red LED will illuminate indicating the module is on and ready for opera¬tion. Alternatively, you
can also press and hold buttons “ON/OPEN” and “OFF/CLOSE” on the RF transmitter for 3 – 5
seconds to power the system on or off.
One Touch Operation:
This operation is fully automated and will stop when proper tension is reached when fully opened
or closed.
To uncover the load, push and hold the button labeled “OPEN” on the relay module or “ON/OPEN”
on the RF transmitter for 1 to 2 1/2 seconds then release. The gear motor will wrap the tarp
around the tarp axle causing the axle to move from the tarped position to the stowed position.
This tarp system can be opened part way and stopped. Anytime you want to stop the tarp system
just hit the “OPEN” or “CLOSE” buttons or “ON/OPEN” or “OFF/CLOSE” on the RF transmitter
and the tarp system will stop. It will not hurt the tarp system to stop part way through the tarping
cycle. When the system shuts down automatically, the system will be set to the recommended tarp
tension. Never travel with the tarp in a partially covered position. The trailer should always be
covered when traveling.
To cover the load, push and hold the “CLOSE” button on the relay module or “OFF/CLOSE” on the
RF transmitter for 1 to 2 1/2 seconds. The springs in the arm will move the tarp from the stowed
position and across the trailer to the tarped position. When the system shuts down automatically,
the system will be set to the recommended tarp tension.
Incremental Operation:
To inch the tarp in either direction press the “OPEN” or “CLOSE” buttons on the relay module
intermittently.
Press and Hold Operation:
To uncover the load using the press and hold feature, push and hold the button labeled “OPEN” on
the relay module or “ON/OPEN” on the RF transmitter. The gear motor will wrap the tarp around
the tarp axle causing the axle to move from the tarped position to the stowed position. Release
the button when the system shuts down automatically. This tarp system can be opened part way
and stopped. Anytime you release the switch the tarp system will stop. It will not hurt the tarp
system to stop part way through the tarping cycle.
Never travel with the tarp in a partially covered position. The trailer should always be covered
when traveling.
To cover the load using the press and hold feature, push and hold the “CLOSE” button on the relay
module or “OFF/CLOSE” on the RF transmitter for greater than 2 ½ seconds. The springs in the
arm will move the tarp from the stowed position and across the trailer to the tarped position.
Release the switch when desired during operation or when the system shuts down automatically.
