Alsco 3 Level Hoist Operational Function.
Assuming hoist is at the bottom position with no linen bags
loaded onto machine.
1/ Operator disengages and opens locked perimeter gate with
“Lock/Unlock” switch located on the operator panel. The
perimeter gate will only disengage when hoist is at this
bottom position.
2/ Operator presses the green push button located on the
hoist frame to allow one bag lock to open. This allows the
operator to place ONE trolley onto the hoist rail. This
switch is only accessable and functional when the perimeter
gate is opened and hoist is at the bottom position. Once the
trolley is in the correct location at centre of hoist rail,
operator then switches the same switch as described above to
close the hoist rail gate.
3/ Operator wheels in tub with full bag into hoist area
underneath the trolley hook and slings bag onto the hook.
4/ Operator closes perimeter safety gate and engages the
“Lock/Unlock” switch located on the control panel.
If all gate switches are closed correctly, “Hoist enabled”
light will illuminate on panel indicating hoist is ready for
use.
5/ If bag is going to the middle rail, operator presses “Mid
from bottom” push button until hoist comes to a total stop at
the middle location. If bag is going to the upper rail,
operator presses the “Top” push button.
6/ Once hoist is at the desired location, operator activates
“Open/Close” switch on panel. Only those gates that are
required to move bag from hoist to main rail will open.
7/ When bag has been moved and is clear from the gates,
operator then switches the “Open/Close” switch back to close
and the locks will shut. Only after all locks are correctly
closed, will the hoist be ready for use. From this point, the
operator is free to move the hoist to either the bottom
location or the top location by pressing the appropriately
labelled push buttons on the control panel.

Alsco Hoist Safety Notes.
– Hoist is only operational when all perimeter gates and
hoist rail locks are closed correctly. The “Hoist
enabled” light on the control panel will reflect this.
– The perimeter gate will only open when the hoist is at
the bottom position.
– Only hoist and main rail locks that are required to open
so as to move the trolley from one rail to another will
open.
– Hoist has an air pressure switch allowing the hoist to
only be operational with a minimum of 6 bar air pressure.
– If any safety conditions are breached whilst the hoist is
not in a safe location, the safety controller will
activate the motor invertor safety function and enable
the motor brake.
– Flashing beacon and sounder will activate whenever the
host is in motion.

Alsco 3 stop linen hoist electrical install instructions.
Please carefully read and understand these instructions before starting the hoist installation.
Warning! It is imperative that that the personel who are responsible for assembling this hoist have a firm
understanding of electrical safety circuits, frequency inverters and 3 phase braked motors.
STAGE 1
– Mount control box in desired position on stand. Consider the operator who will be using the
hoist daily for best position. See pic of other install.
– Mount supplied 3 pole isolator on control box stand and run 2.5mm 4c + E - OC cable from
isolator to 10A MCB located inside control panel and connect temporarily to U/V/W on VSD
(this bypasses the safety contactor so we can operate motor manually), leaving power off.
– Connect mains from factory DB CB (20A supply) to previously mounted isolator.
– Mount and bolt 2 x 40mm x 40mm Combination strut (back to back unistrut not supplied) to
rear of hoist as per pic 1. Tabs will need to be fabricated to hoist bottom plate and top plate to
suit. Ensure unistrut is square to rest of hoist.
– Install unistrut and tray from control panel to hoist structure.
– Run EMC 3C + E motor cable from VSD to motor mounted at top of hoist and connect in star.
– Run and connect as per schematics, 3 core (0.75mm2) cable from BMK brake rectifier inside
control panel to motor brake terminal/wire inside motor conduit box.
*NOTE! If there is an internal brake module located inside the motor terminal box, remove it.
The motor manufacurer sometimes installs these from factory. It is not used! Disonnect so you
will have only the three (red, white, blue) wires to connect. Term 13 – 4a (red), 14 – 3a (white),
15 - 5(blue).
– Mount braking resistor on unistrut and connect to VSD BRK+ and BRK – with 2c + E cable.
– At this point, check all connections and ensure they are correct.
– If fabricator/fitter has installed left and or right fixed linen rail to meet the new hoist rail, follow
these next instructions.
– CLEAR ALL PERSONNEL FROM MACHINE– and energise control via main CB. Watch for
any undesirable reactions from the VSD or the machine. NOTE! The VSD has been correctly
programmed and tested before leaving our workshop.
– If required by the fabricator to finish rail ends, you can now run the motor in LOC control and
with 10rpm only by carefully following the VSD instructions in the VSD manual.
REMEMBER! The motor brake is energised! To release brake, bridge VSD term no 17 and 19.
DOING SO WILL ALLOW THE HOIST HEAD TO SLOWLY FREEFALL SO AGAIN KEEP
PERSONNEL CLEAR!
– Allow fabricator to complete the rail ends with the help of you manually driving hoist up and
down as required.
STAGE 2
– Shut off machine reconnect mains to top of control board CB!
– For 3 level hoist only - Mount M30 prox (Mid ramp prox I5) to unistrut using M30 sensor
bracket to approx same height from floor as middle fixed rail.
– Mount M30 prox (Top ramp prox I13) to unistrut approx 150mm lower than upper fixed rail.
– Mount M30 prox (Bottom pos prox I11) to unistrut approx 1500mm from floor level.
– Mount JB1 at a location right at top of hoist and install 2 x 25mm PVC glands in JB1.
– Run M30 prox cables to JB1 leaving small loop at prox for future adjustment.

– Screw ramp plate to hoist structure as shown in pic 2. Must be in centre alignment of previously
mounted M30 prox's.
– Mount JB2 next to ramp plate as shown in pic 2 also. Install 2 x 25mm glands as shown.
– Mount cable chain angle bracket to strut approx 2/3 up hoist height from floor level as shown in
pic 3.
– Mount other end of cable chain to hoist head just below JB2 as per pic 4. NOTE – cable chain
must not be under any strain when hoist moves its full distance. This includes to bump stops!
– Run C1 and C2 (both 12 core cable) from control panel terminals to JB1 and JB2 terminals.
(JB2 via cable chain) and connect as per cable schedule/schematics attached.
– Work with fabricator as to the position of the hoist rail and stoppers and mount valves and
stoppers as shown in pic 6. Stoppers to be mounted close enough to end of hoist rail so as to not
let a trolley between the hoist stopper and, for example the top rail stopper when hoist is at top
position.
– Connect valves and as per wiring diagram.
– Mount air regulator to control panel stand and run 6mm line to all four valves. Connect to main
air and leave air pressure off.
– Work with fabricator as to the position of the rail accuracy prox's (I6 and I4) and mount. Note!
Only I6 if hoist is two level and both I6 and I4 if its a three level model. Gap recommendation is
no more than 5mm. See pic attached.
– Mount hoist head Open/Close switch to front of hoist as per pic.
– Run 2 x accuracy prox's, Open/Closed switch, stopper safety switch and air line through conduit
and connect in JB2 as per schedule.
– Mount fixed rail stoppers close to rail end. Connect safety switches and valves in JB1 as per
schedule.
– After checking all connections, power up machine.
– Press “Reset” on front of control panel. Emergency relay should energise.
– Test operation and motor direction by briefly pressing the “TOP” push button.
– Check rail clearance carefully!
– Check all proximity switches are wired correctly by ensuring their corresponding inputs turn on
at the safety PLC.
– Check hoist operation by pressing and holding the “TOP” push button. Hoist should ramp to
slower speed once the top ramp prox makes, then come to a stop once the top accuracy prox
makes. This is the same for the other levels.
– Small adjustments will need to be made to the proximity sensors to gain optimum positioning.
After doing these, recheck hoist operation before handing over to production.
