Installation
Unpacking
Before handling the control, read page iii, Electrostatic Discharge Awareness. Be
careful when unpacking the electronic control. Check the control for signs of
damage such as bent panels, scratches, and loose or broken parts. If any
damage is found, immediately notify the shipper.
The ProAct™ actuator will come in a separate carton from the control. Inspect
the carton for damage. The actuator is a rugged, heavy device and shipping
damage is unlikely. Particularly inspect the receptacle and terminal shaft for
possible damage.
Power Requirements
The ProAct II control system requires a voltage source of 18 to 32 Vdc (24 Vdc
nominal) uninterrupted power supply. Maximum power consumption is 125 W at
rated voltage. The ProAct I system requires a voltage source of 8 to 32 Vdc (12
or 24 Vdc nominal). Maximum power consumption is 50 W at rated voltage.
To prevent damage to the control, do not exceed the input voltage
range.
If a battery is used for operating power, an alternator or other battery
charging device is necessary to maintain a stable supply voltage.
To prevent damage to the control, make sure that the alternator or
other battery-charging device is turned off or disconnected before
disconnecting the battery from the control.
Control Box Location Considerations
Consider these requirements when selecting the mounting location for the ProAct
control:

adequate ventilation for cooling

space for servicing and repair

54 inches (1.4 m) of connecting cord is provided with the Hand Held
Programmer. If the location does not allow comfortable use of the
programmer, an extension cord should be obtained at the time of installation.
The RS-422 communications will allow a lengthy extension cord.

protection from direct exposure to water or condensation-prone environment

protection from high-voltage or high-current devices, or devices which
produce electromagnetic interference

avoidance of vibration

selection of a location that will provide an operating temperature range of
–40 to +70 °C (–40 to +158 °F).
The Digital Speed Control must NOT be mounted on the engine.
