OPERATION
Fig. 6
!
WARNING: All moving parts, such as the Group of rising and
falling pressure plate may cause damage to the upper extremities.
Do not approach with hands for the moving parts during
operation of the equipment.
During the ascent and descent of the hoist keep hands pressing
plate and the rim of the container material.
Keep hands away from pump during operation material priming
piston and compressed air is supplied to the unit whenever.
Before performing any maintenance or repair, disconnect the
compressed air supply and arrange for decompression of the
pump and of the ram.
INK DRUM INSTALLATION
1. Check that the control cabinet lever is in the "NEUTRAL" position
(centre).
2. Slide the 200 kg drum along the base of the inductor. It will stop up
against the inductor limiters. Always use drums that are compatible
with this unit. Do not use damaged drums as they can cause the
inductor plate to get stuck in the drum.
3. Unscrew the bleed rod from the inductor plate, keeping it nearby.
4. Move the control cabinet lever to the "DOWN" position.
INK SUPPLY
1. Select the "DOWN" position in the hoist control cabinet, the
inductor plate will compress the ink, priming the pump.
2. Start the pump by placing the "Pump Control" valve in the "ON"
position.
3. The pump/inductor can now supply ink through the output hose
until the drum is empty, the speed of emptying can be monitored
by opening and closing the end of the output hose. When the
inductor plate touches the bottom of the drum the inductor plate
sensor is activated the alarm sound rings and stops the pump.
4. Before raising the inductor to replace the drum, the pump control
valve must be in the "OFF" position.

CAUTION
To raise the inductor for the first time:
1. Ensure there is nothing above the hoist. In addition, read the
WARNINGS AND PRECAUTIONS on page 2.
2. Move the control cabinet lever to the "UP" position. Do not touch
any part of the unit while it is moving!
3. Lift the inductor plate higher than the top of the drum. Stop the
hoist ascending further by moving the control cabinet lever to the
"NEUTRAL" position (centre).
To raise the inductor, (normal operation):
1. Before raising the inductor, the pump control valve must be in the
"OFF" position.
2. With new gaskets the pressure indicated on the "Ram Control" dial
must be 6-7 bar (with softer used gaskets the pressure may be lower,
to reduce slight fluid leakage). To adjust the inductor air pressure,
partially remove the "Ram Control" regulator control so it can be
turned, clockwise to increase the pressure and anti-clockwise to
reduce it. To set the pressure, push the regulator towards the control
box and lock it again.
3. Move the control cabinet lever to the "UP" position.
4. Lift the inductor plate higher than the top of the drum. Stop the
hoist ascending further by moving the control cabinet lever to the
"NEUTRAL" position (centre).
5. Let the inductor plate descend through the drum. When the air
stops and the ink starts to flow through the bleed hole, stop the
inductor by moving the control cabinet lever to the "NEUTRAL"
position (centre).
6. Insert the rod and tighten it correctly. Place drum fixing.
7. The unit is now ready to work with. The pump should already be
operative.
!
CAUTION: Not dry run the pump: it could damage the
pneumatic motor and ruin the seals.
5. Move the control cabinet lever to the "UP" position. In this position
the cylinders go up in the unit and a current of air enters the drum
to push the inductor plate.
6. Lift the inductor plate higher than the top of the drum. Stop the
hoist ascending further by moving the control cabinet lever to the
"NEUTRAL" position (centre).
