Function
Description
0 0 1MTA4-1
Bearing Seal Deflated
On machines with a positive
pressure (pressure greater than
that of the atmosphere) in the
bearing housing, this circuit
closes when the pressure drops.
1 1 1MTA4-2 Chute Down Left Lock
This circuit closes when the
lower-left chute lock actuates
(one of two inputs actuated
when the chute is in the down
and locked position). The chute
must be fully down for loading.
2 2 1MTA4-3
Inverter Input
This circuit opens when the in-
verter is enabled and closes if an
inverter fault occurs.
3 3 1MTA4-4 Passed Wash Position
This circuit closes when the ma-
chine attempts to tilt to the dis-
charge position before an
extract, which triggers the
“Can’t Find Wash Position” er-
ror (see Can't Find Wash
Position).
4 4 1MTA4-5 Wash Position
On machines that tilt, this circuit
closes when the machine is in
the wash position.
5 5 1MTA4-6 Load Position
On machines that tilt, this circuit
closes when the machine is in
the load position.
6 6 1MTA4-7
Do Not Allow Chemi-
cals (ChemSaver); Tim-
er Stop
If the input is grounded and the
machine still has chemicals to
inject for the step, this input is
“Do Not Allow Chemicals.” If
all chemicals have been deliv-
ered or no chemicals are pro-
grammed, this input is “Timer
Stop.” Note: Once a chemical
signal starts it will not stop.
