ADJUSTMENTS

SPIN DRIVE CONTROL BOARD (SDC)

The Spin Drive Control Board has four potentiometers, two switches and one dial. These

potentiometers,swtiches and dial have been set at the factory to the positions shown on Figure 17.

In the Relief Grinding Mode--

The Torque Shut Off mode selector allows you to turn on or off the Torque Shut Off feature. When switch 1

is set to ON, the board will decrease the spin motor torque once the shut time is achieved after leaving the

right proximity sensor. The amount of time it takes before the torque is decreased is set with the Torque Shut

Off Delay dial. The spin motor torque will be increased to the higher value once the right proximity switch is

activated again. If the Torque Shut Off selector is in the OFF position the torque will remain constant during

relief grinding. This should be set to OFF.
Torque Shut Off Delay dial is used to set the duration of time before the torque is decreased after leaving the

right proximity sensor during relief grinding. If the dial is turned clockwise (higher number) the higher torque

value will stay on for a longer period of time.
The Relief Speed (RSP) and the Relief Torque Pot (RTP) interact with each other. The (RSP) is located on the

spin board as a remote speed preset at 12:00 (20 Volts DC). The (RTP) is located on the control panel and is for

relief torque adjustment.

Relief Speed Pot (SPEED) when rotated clockwise will increase spin drive speed (the speed at which the reel

indexes to the next blade). This speed should never be above the 3:00 setting.
Relief Torque Pot (TORQ) is used to vary the reel to finger holding torque for relief grinding. The

recommended starting point is 30 in/lbs of torque setting. Never adjust the (RTP) potentiometer dial past the

red line marking. Setting the reel to finger torque to high could cause the spin motor system to not operate

smoothly.
Relief Idle Torque Pot (ITP) is used to vary the reel to finger holding torque once the shut time is achieved

after leaving the right proximity sensor if the Torque Shut Off Selector is set to on.

n the Spin Grinding Mode--

The Spin Torque Potentiometer (STP) and the Spin Speed Pot (SSP) interact with each other. The (STP) is

located on the spin board as remote torque preset at 2:00 for torque setting. The (SSP) is located on the

control panel and is for spin speed adjustment.
Spin Torque Pot (STP) controls maximum torque allowable in the spin grinding cycle only. This should never be

adjusted past the 3:00 position. If the reel does not turn check that the reel is free turning by hand spinning

with the power off and the spin drive disconnected.
The Spin speed Pot (SSP) controls reel spin speed, adjust as required. This controls the spin drive speed for

spinning the reel.

IR COMP Pot--

The IR Compensation is factory set at 9:00.
Regulation of the spin or relief grind spin motor may be improved by a slight adjustment of the IR COMP pot

clockwise from its factory-set position. Overcompensation causes the motor to oscillate or to increase speed

when fully loaded. If you reach such a point, turn the IR COMP pot counterclockwise until symptoms just

disappear.
