• 0.01 Tach Cal Input 1 - This input is used to program PLC for EOS settings ONLY! Not used during normal
operation.
• 0.02 Tach Cal Input 2
- This input is used to program PLC for EOS settings ONLY! Not used during normal
operation.
• 0.03 Not Used
– No Connection
• 0.04 High Flow
– This Input monitors the high flow request switches. These switches are the equivalent switches
used for throttle advance on throttle advance equipped unit. This is a momentary switch located on the left front
corner of the body, a limit switch operating off the control rods, and optional switches located in the rear control
stations.
• 0.05 Pressure Switch - This Input monitors the low torque pressure switch. The pressure switch will provide a
+12 volt signal when the switch set point is exceeded. This input will turn off pump 2.
• 0.06 Not Used
– No Connection.
• 0.07 Not Used
– No Connection.
3.0 OUTPUTS
10.01 Pump P1 - This output operates Pump P1. This pump will only operate at rpms less than 1000. A high
transmission temp signal or a low torque pressure switch signal will disconnect this pump.
Conditions Necessary to Turn 10.01 “ON”
Function or Component
Status I/O #
A. Alternator Good 0.00 (See note)
B. Low Torque switch Off 0.05
C. Tailgate Slide Switch (Throttle Adv.) On 0.04
Note: With the above conditions met 10.01 will turn on when:
1. Pump switch is on.
2. Engine speed is greater than 550 RPM (below 333 RPM is an engine speed fault),
below 800 RPM to engage and will disengage at 1000 RPM.
3. The low torque pressure switch is below its set point.
10.03 Pump P2
- This output operates Pump P2. This pump will engage up to 1800 rpm and disengage at 2000 rpm.
A high transmission temp signal or an engine droop signal will disconnect this pump.
Conditions Necessary to Turn 10.03 “ON”
Function or Component
Status I/O #
A. Alternator Good 0.00 (See note)
Note: With the above conditions met 10.03 will turn on when:
1. Pump switch is on.
2. Engine speed is greater than 550 rpm (below 333 RPM is an engine speed fault), below
1800 RPM to engage and will disengage at 2000 RPM.
10.06 Calibration Indicator
- This output is a display only output and does not connect to the “real world”. It
indicates the PLC is in calibration mode. It is not used in normal operation
Conditions Necessary to Turn 10.07 “ON”
Function or Component
Status I/O #
A. Calibration input 1 On 0.01
B. Calibration input 2 On 0.02
