Normal Operation
Start Relay on PCB activates and supplies 120
volts to Run and Start winding. Ram starts
downwards.
gt

7
Normal Operation
Centrifugal switch N.C contact opens so start
winding drops out and N.O. contact closes.

8
Normal Operation
The Start relay disengages and the Upper Limit
Switch closes and supplies 120 volts to RUN
winding.

9
Normal Operation
At the same time the upper limit switch
activates, so does the upper limit directional
switch which will allow the Up Start winding to
engage when ready.

10
Normal Operation
When the ram is all the way down, the Lower Limit
Switch is closed, supplying neutral to the UP
Start winding.

11
Normal Operation
The Motor switches direction and begin to turn in
the opposite direction, bringing the ram upwards
gt

12
Normal Operation
The Lower Limit Switch opens and removes the
Neutral to the Start winding. The ram continues
upwards.

13
Normal Operation
When the ram gets to the top position, the Upper
Limit Switch is activated. Power is interrupted
to the Run Winding and the motor stops.

Delay Operation
DELAY START button depressed Door closed. Door

18
Delay Operation
At the predetermined Start time, the Compact
Mode and Start Relays on the PCB activate.
120 volts is
supplied to Run and Start winding via the "C"
terminal of the Upper Limit Switch.

The ram starts downwards.
gt

19
Delay Operation
Centrifugal switch N.C contact opens so start
winding drops out and N.O. contact closes.
gt

20
Delay Operation
The Start relay disengages and the Upper Limit
Switch closes.
gt
lt
21
Delay Operation
Line voltage from the Upper Limit Switch is now
directed through the C and N.O contact
(Now closed) in the Compact Mode
Relay. Voltage is sent through the closed
centrifugal switch contact to the motor run
winding.
gt
lt
22
Delay Operation
The Upper Limit Switch (Directional) is also
switched to the N.C position. It will now be
ready to engage the START UP
winding when required
gt
lt
23
Delay Operation
When the ram is all the way down, the Lower Limit
Switch is closed, supplying neutral to the Start
UP winding.
gt
lt
24
Delay Operation
With Neutral applied to the Start Up winding,
the motor is stopped, allowing the centrifugal
switch contact which has been supplying line
voltage to the Run winding. The motor stops and
the ram is in the COMPACT Mode.

This will stay like this for 2 hours.
gt
lt
25
Delay Operation
At the end of the 2 hour delay, the Compact Mode
Relay releases and engages the N.C contact. This
allows line voltage to flow to the RUN and START
UP windings via the Upper Limit Switch.
gt
lt
26
Delay Operation
The Centrifugal Switch activates and the Lower
Limit Switch opens which removes the Neutral to
the START UP winding. The ram continues upwards.
gt

27
Delay Operation
When the ram gets to the top position, the Upper
Limit Switch is activated. Power is interrupted
to the Run Winding and the motor stops.
