Description
7 7 1MTA4-8
Basket (Cylinder)
Rotating
This circuit closes when the ma-
chine cylinder is turning.
8 8 1MTA4-11 Excursion
This normally closed circuit
opens when the excursion
switch actuates due to imbalance
during high-speed extraction.
9 9 1MTA4-12 Can’t Close Bifold
The loading device sends this
signal to the machine to indicate
it is not safe to close the bifold
door.
10 10 1MTA4-13 Brake Pads Worn
On machines with a mechanical
brake, this circuit closes to sig-
nify that the brake pads need to
be changed.
11 11 1MTA4-14 Brake is Off
On machines that have a brake,
this circuit closes when the
brake is released. This occurs
when the cylinder can turn
safely.
12 12 1MTA4-15
Door Open Desired
This circuit closes when the op-
erator presses the door open
button.
13 13 1MTA4-16
Speed Limit Desired
On older machines with the “Ex-
act Extract” option, this circuit
closes when the machine is out-
of-balance. When this system
opens the circuit, the extract step
resumes at the speed the cylin-
der was turning when the circuit
closed.
14 14 1MTA4-17 Coarse Balance
On balancing machines, this cir-
cuit closes when the machine is
out of balance after low extract,
which causes a recycle.
15 15 1MTA4-18 Three Wire
This circuit closes when all 3-
wire safeties are satisfied and
the circuit is engaged.
