11.3.2 Battery Circuit Requirements
CAUTION
IMPROPER WIRING CAN CAUSE ELECTRICAL NOISE OR UNRELIABLE OPERATION AND MAY
DAMAGE THE CONTROL SYSTEM OR OTHER COMPONENTS. ALL POWER CONNECTIONS
MUST BE FREE FROM FOREIGN MATERIALS, INCLUDING PAINT, WHICH MAY INTERFERE WITH
PROPER CONNECTION. A RELIABLE 30 A MAXIMUM FUSED POWER CIRCUIT MUST BE
PROVIDED FOR THE CONTROL SYSTEM. CATTRON RECOMMENDS THE POWER
CONNECTION BE MADE DIRECTLY TO THE BATTERY WITH THE FUSE ELECTRICALLY CLOSE
TO THE BATTERY. GROUNDING THROUGH FRAME MEMBERS IS NOT RECOMMENDED. ALL
CIRCUIT PATHS MUST BE CAPABLE OF CARRYING ANY LIKELY FAULT CURRENTS WITHOUT
DAMAGE. DO NOT REVERSE THE BATTERY POLARITY. ATTEMPTING TO CRANK THE ENGINE
WHEN THE POLARITY OF THE BATTERY CONNECTIONS IS REVERSED MAY DAMAGE THE
CONTROL SYSTEM.
11.3.3 Battery Positive Connection
The electronic control system operates on either 12 VDC or 24 VDC electrical systems. The unswitched battery
positive connection to the control system is made at the weatherproof connector. The control system provides
switched positive battery protected by solid-state MOSFETs. These outputs include integral protection against
overloads and short circuits.
Powering the control system through a 30 A fused dedicated circuit reduces the possibility of system damage.
CAUTION
DISCONNECTING THE BATTERY WHILE THE ENGINE IS RUNNING MAY RESULT IN DAMAGE TO
ELECTRICAL COMPONENTS. WHEN USING A BATTERY DISCONNECT SWITCH, CATTRON
RECOMMENDS USING A TWO POLE SWITCH TO DISCONNECT BOTH THE BATTERY AND
ALTERNATOR OUTPUT.
Note:
A maximum of three ring terminals should be connected to a power stud to ensure integrity of the connection.
The use of more than three terminals can cause the connection to become loose.
11.3.4 Voltage Drop
If control system voltage drops below 6 V for more than 0.1 s, the control system may reset, causing the self-test
to reactivate. Resetting the control system is equivalent to quickly turning the key switch to OFF and then back to
run without starting the engine. Voltage drops can be caused by a discharged battery, transients from external
