Installing the rapidCAST System
Environmental Conditions
The RapidCAST is rated to IP65. All exterior components are sealed and water-tight when the cables are
mated. Dust caps should be installed on connectors when they are not in use.
Overall, the system has very good UV resistance, but should not be left outdoors for extended periods of
time, i.e. months.
When installed in cold/wet environments near freezing (0°C), ice may form on the system. Due to the
mechanical nature of the system, it is necessary to prevent and de-ice the system prior to and during oper-
ation. Store the system inside or cover it when not in use to prevent icing.
Hot environments (greater than 30°C) require careful consideration of the environmental conditions. The
radiative heat from the sun and ship deck can cause ambient shipboard temperatures to exceed 40°C.
When operating in a hot environment the following items should be considered:
1.
Deep casts at higher ship speeds will generate the most heat because the motor is working hard
for an extended period of time.
2.
Shallow casts at lower ship speeds will generate the least amount of heat.
3.
Consider reducing the duty cycle of the system and allow it to cool off between casts if heat gener-
ation is excessive.
4.
Remove the orange side cover on the motor side during operation to assist with cooling.
The RapidCAST system monitors the temperature of the Motor Controller which has a maximum allowed
temperature of 70°C. If the Motor Controller temperature reaches 70°C, the brake will engage and the
motor will no longer be powered. The Motor Controller will re-activate when the temperature drops be-
low 70°C. If this condition occurs, the user should re-evaluate the duty cycle.
