Adjustment Procedure for Closure Timer using R19/R37

The closure timer determines how much time is spent raising the top to the safety

stop position. In order to function properly the top must reach the safety stop

before the timer expires. If the timer is too short then the top will hang prior to

the safety stop and will end up in the safety position until a subsequent Top

Close command is issued. If the timer is too long then the top will spend extra

time in the safety position prior to closure. ***EXTREME*** care should be taken

to avoid touching any part of the mechanism until the operations are completed.

Fine adjustments in the Hardtop to Safety time are made using the R37 screw

adjustment accessible through the front panel using a jewelers screwdriver. A

total range of approximately 5 seconds is available. Coarse adjustments can be

made by changing the value of R19. For every 10K change in R19 the timer

range will shift approximately 1 second.

Access R37 through the front panel

R37 access hole 

Timer too short (Top hangs prior to safety stop)

 Turn R37 counter-clockwise (CCW) to lengthen the timer. Each full turn

will add approximately 1 second to the timer.

 If a timer longer than approximately 27 seconds is needed then R19 may

need to be increased

Timer too long (Top spends excessive time at safety stop)

 Turn R37 clockwise (CW) to shorten the timer. Each full turn will subtract

approximately 1 second from the timer.

 If a timer shorter than approximately 22 seconds is needed then R19 may

need to be decreased

Changing adjustment range using R19

 R19 default value is 174K ohms

 Each increase of 10K in the value of R19 will shift the timer range higher

by approximately 1 second. For example if R19 is increased to 185K then

the timer range will move from 22-27 to 23-28 seconds.

 Each decrease of 10K in the value of R19 will shift the timer range lower

by approximately 1 second. For example if R19 is decreased to 162K

then the timer range will move from 22-27 to 21-26 seconds.
