Alfalaval ThinkTop Basic User manual

3. 4. 5.
Installation on air
actuators:
1. Remove the cover by loosening the
four cross recess screws.
2. Separate the adapter from the base
by loosening the three recess screws
on top of the base.
1. Fit air fittings on actuator.
2. Position packing retainer in recess on
actuator top.
3. Fit counter nut and indicator (magnet)
on actuator rod. Engage approx. ¼”
thread. Tighten counter nut and
indicator with two wrenches.
1. Place the two O-rings in the grooves in the
bottom of the adapter. Then place the adapter
on the actuator top. The small O-ring must be
positioned over the air hole on the actuator.
2. Fasten the adapter with the four 5/16” Allen
screws.
Mount the base on the adapter in the
position needed (can be rotated 120°
in both directions). Note that one of the
screw towers on the adapter has a guide
recess (see on drawing).
Fit ¼” air hose to ThinkTop and actuator
(see drawing “Air Connections” (point 8
next page)).

1. Install cable (if not pre-installed) through
the cable gland (see drawing “Electrical
connection, internal” (below).
2. Tighten cable gland.

1. Perform set up routine.
2. Mount the cover.
Note! The IR keypad may be used to set
up the unit. To energize the valve, use
separate air supply or be in radio contact
with the control room.

Electrical connection, internal:
*) Note!
Terminals 24, 25, 26 and 27 can be used for external seat-lift sensors as well as for
any digital input. Always use an external PNP sensor. Two external signals can be
connected, they are associated with feedback signal 3 (seat-lift 1) and 4 (seat-lift 2).
External sensor must always be a 8-30 VDC PNP 3 wire sensor. Connect (-) common
on terminal 27, and (+) common on terminal 26. The signals from the external
sensors are associated as follows: sensor signal on terminal 24 (seat-lift 1) associated
with feedback 3 (seat-lift 1), and sensor signal on terminal 25 (seat-lift 2) associated
with feedback 4 (seat-lift 2).
**) Note!
Jumper present = PNP. If changing the function a power recycle is necessary. The
selection NPN/PNP is done by the jumper.
***) Note!
Internal connections: Terminals for connection for the solenoids mounted internally in
the control head. The number of solenoids actually mounted in the control head
could be 0 - 3. The signals are taken directly from the terminal row.
****) Note!
If using external sensor, the sensor must be active/activated when performing a
set-up routine of the control head.
Note! Remember to isolate wires that are not in use.
Very Important!
Please read detailed instructions in instruction manual ESE00353.
