fully inspecting the following:
A)DC Power Source
1. Ensure that the Processor(s) and Clutch power is connected to a properly
charged 12 or 24VDC battery through a 10 Ampere circuit breaker.
2. To ensure reliable power to the Processor(s) even with a failure of single bat-
tery, the APS (Automatic Power Selector) may be used as shown in Figure 2:.
B) Component Locations
1. Control Heads - There are virtually no restrictions regarding the location of
the 400 Series & MC2000 Series Style Control Heads, as long as the bottom is
protected from the environment. In the case of the 700 Series Control Heads,
this concern doesn’t even exist.
2. Processors - The Processors are typically mounted anywhere in the Engine
Room, while maintaining a minimum distance of 4 feet
(1,22m)
from sources of
high heat and EMI or RFI energy.
C) Component Condition
1. Control Heads - Inspect for any signs of corrosion due to water incursion.
Ensure that all fork connectors are properly secured to the terminal strip.
2. Processors - Inspect the Processors for any signs of physical damage.
D)Interconnecting Wiring
1. Inspect the Harness’s Pins and Sockets for bent pins or any signs of corrosion.
