MAX POWER 

 
All wires should be carefully 

labelled to reduce the chance of error

 and simplify 

checking and troubleshooting.  
 
All wire ends for terminals should be tinned before inserting into terminal blocks. 

 

The control system of the RETRACT requires 30 amps of stabilised 24 v dc power.  
The 24 volt input power is automatically transformed to produce 12 volts for the 
control panel use 

control panel only

.  

The major power consuming components of the RETRACTS electrical system (the 
raise/lower unit, the directional valve solenoids, and the electromagnetic clutch) are 
supplied with 24 volts 

from the

 control box.  

 
Complimentary alarms may be added at will  (over heat, low oil, etc etc)  
Switching the thruster 

system

 on is achieved by a two-pole 32-amp circuit breaker 

(not supplied by Max Power), which should normally be located on the main electrical 
panel.  
 
 

CONTROL SYSTEM PLC (NON MAX POWER SUPLLY) 

 

If the max power control box is not used an integrated PLC can be used to replace it. 
If this is the case The PLC must be programmed to follow the following sequences. 
It will also require.  
 
8 input channels (inductive proximity switches) 2 up 2 down 2 locked 2 unlocked. 
 
4 output channels (switching 24v 2amps) up down motor supply, up valve, down 
valve, left thrust, right thrust.
