There are two classes of faults the first is a system fault. A system fault indicates a possible electrical problem with some part of a
specific circuit. The second is a Critical Fault. A critical fault indicates that a problem is occurring which has or will shut the
hydraulic pump system down.
6.04.01: Critical Faults
Fault #31- High Transmission Temperature (optional equipment)
Operate in Gear At Idle (O.I.G.A.I) units monitor the temperature of the transmission sump fluid and the fluid flowing out of
the torque converter to the cooler. This fault will be set when either of these temperature levels exceed operating range. The
maximum operating temperature for the transmission sump fluid is 250 F. The maximum operating temperature for the
converter out fluid is 300 F.
Indication: A. The transmission temperature has exceeded a safe operating range.
B. An open has occurred in the Trans. Temp. Input circuit.
Disabled Functions: Hydraulic Pump
Fault Reset: In order to reset this fault:
1. the trans. must be placed in neutral range
2. and the engine must be running at or above idle speed
3. And the trans. temperature must cool to a safe level and remain at a safe level for three minutes.
Note: This fault is option dependent and is only available on with Operate In Gear At Idle (O.I.G.A.I) units.
Fault #32- Filter Bypass Shutdown (standard equipment)
The hydraulic system has been operating in bypass condition in excess of 6 hours set by the Start Filter Shutdown
parameter.
Indications: The hydraulic filter needs servicing
A.
Disabled Functions: Hydraulic Pump
Fault Reset: Cycling the System Power Switch will allow three minutes of further operation or
service hydraulic filter
Fault #33- Side Door Interlock (standard equipment)
The CORTEX Controller has lost the signal from the “Side Door Switch” during operation of the hydraulic Pump(s).
Indications: A. The side door has been opened during operation of the unit
B. An open has occurred in the Side Door input circuit.
B. C. The Side Door proximity switch has failed.
Disabled Functions: Hydraulic Pump
Fault Reset: Cycling the System Power Switch
Fault #34- Low Hydraulic Oil (optional equipment)
The CORTEX Controller has lost the signal from the “Oil Level Switch”.
