![](/html/44/4440/4440261ebba5e96779d5476fdfdb783da6f3274cc86649c63aafaea6470a3569/bg12.png)
Dryer External Connections
Once assembled, installation requires connection of: pneumatic air line, electrical, intake and output material
lines.
Compressed Air Connection
Connect an air supply to the air regulator’s IN port using a female 1/4” NPT
pipe fitting.
An operating air pressure of 80 psi (5.5 bar) while the vacuum
generator is running is required for proper operation of the Dryer.
Setting the air pressure to 85 psi while the machine is idle will usually
attain the desired 80 psi while the vacuum generator is running.
If your air supply has oil in it, add an oil separator
(coalescing filter). Oil in the air will combine with dust drawn from the
Vacuum Chamber forming a paste inside the vacuum generator. It
will stop working and require cleaning.
Observe the air pressure gauge to be sure the pressure maintains 80
psi (5.5 bar) while the vacuum generator is running as you check and
adjust the regulator. If pressure drops below 80 psi, adjust the
regulator. If the pressure cannot be maintained at 80 psi (5.5 bar) while
the vacuum generator is running, then the air supply line is not
adequate.
Do not supply Dryer with a lubricated air supply. Damage
to Dryer may result. Use only a clean, dry, oil-free air
supply.
Pinch Hazard - Keep fingers clear of seal deck, the
mating surface above the Vacuum Chamber seal.
When air pressure is turned on and the Vacuum
Chamber Lift Switch is flipped up, air cylinders lift the
Vacuum Chamber off of the slider rails and up to the
seal deck closing the gap between the top of the
Vacuum Chamber and the seal deck.
KEEP FINGERS CLEAR
![](/html/44/4440/4440261ebba5e96779d5476fdfdb783da6f3274cc86649c63aafaea6470a3569/bg13.png)
RISK OF INJURY! Only
qualified technicians
should make electrical
connections.
Connect Main Power
The electrical cable located on
the left side of the Dryer on the
power box supplies the power
to the Dryer. Within the cable
are four wires. Three of the
wires are black and labeled with
a number: 1, 2, and 3. The
fourth wire is a green/yellow
wire and is the ground wire.
Connect power to a properly fused disconnect.

![](/html/44/4440/4440261ebba5e96779d5476fdfdb783da6f3274cc86649c63aafaea6470a3569/bg14.png)
Confirm Correct 3-Phase Electrical Connection
THREE PHASE Unit - CONFIRM proper 3-Phase power connection prior to loading
material. Failure to confirm proper 3-phase connection can result in reversed blower
rotation and damage to blower if the blower sucks in material from heating hopper rather
than blow heated air into heating hopper.
To confirm proper 3-phase connection following these instructions:
Turn power on using main power switch.
There are two methods to confirm proper 3-phase
connection:
Incorrect 3-phase connection will result in reversed
blower rotation. Both methods for checking correct
3-phase connection involve testing the blower
rotation.
Method one requires the disconnecting the 2-inch hot
air hose from the heating hopper and manually
turning on the blower. The air from the blower should
blow out of the 2-inch hose. Air should not suck into
the hose. If air does not blow out and sucks in, the 3phase connection is NOT correct.
Method two requires the removal of the left side
panel to view the blower and confirm blower rotation
on power up. Rotation must be clockwise as
indicated by the red arrow.
1. From the Main Screen press
Manual Operations.
2. Press Blower Test.
3. Press the Blower button once to turn ON the
Blower. Press again to turn OFF.

This section will help you understand what the dryer is doing during operation from a cold start. There are 3
concurrent operations. Heating, Vacuum and, Retention. Cold startup begins with Preheat. Preheat only
occurs before the first cycle of the dryer’s initial startup, otherwise each cycle begins with material heating.
The vacuum operation pulls and holds a vacuum on the material for at least the Vacuum Time Set-point (or
longer if material remains in the Retention Hopper). The Retention operation holds the dried material in the
Retention Hopper. If equipped with the optional membrane air dryer, the material will be blanketed with hot
dry air until it is conveyed away.
Important: Inspect the VBD, verify that machine is clear of all material from heating hopper, Vacuum
Chamber and Retention Hopper. To facilitate a Clean Out, use the Clean Out function accessible from the
home screen.
Startup and Operation Instructions
1. ENSURE HATCH IS CLOSED. There is a hatch located on the
upper Heating Hopper. Ensure all 3 latches are closed. Also,
be sure the removable Lower Retention Hopper is in place.
2. Load material into the Upper Heating Hopper. Wait for the
Heating Hopper to fill with material before starting the Dryer.
3. Turn on Main Power by rotating the 25 AMP Main Disconnect
Handle to the Red ON position. This powers up the VBD-150
Dryer.
On initial power up of the VBD, the Control Panel powers ON
automatically. If the main power is ON but the Control Panel is
OFF, press and hold the Red Power Button located on the
Control Panel for 2 seconds. (Note: The VBD’s Control Panel
can be powered OFF without powering down the Main Power
by pressing and holding the Red Power button for 4 seconds).

4. On the Home Screen:
T1 Inlet Temp Setpoint – This is heat hopper inlet temperature. By
the end of the preheat cycle time, all material in the Heating Hopper
will be heated to this temperature. By default, the Setpoint
temperature is set to 150°F. See Recommended Drying
Temperatures on page 29 for general temperature recommendations
or contact the material manufacturer.
Preheat Time – This is the duration of heating from a cold start.
Vacuum Time – This is the minimum duration of a vacuum cycle.
Actual vacuum cycle times will vary according to the throughput. The
default vacuum time is 20 minutes. In the vast majority of drying
operations, this time is adequate and does not need to be adjusted.
Special circumstances may require different vacuum times. Please
consult Maguire Dryer Technical Support for additional information.
Press the setpoint field to adjust the setting. Use the on-sceen
keypad to enter the setpoint and press the green check to complete
the setting adjustment.
5. Press the START button to start the dryer.

What is happening when the dryer is running:
During the Pre-heat operation material in the heating hopper is brought up to temperature (T1s).
Preheat time is determined by the specified Preheat Time on the Pre-Start screen (timed preheat,
default 35 minutes) or by the Preheat Setup Auto option, which sets an inlet to outlet temperature delta
and a minimum preheat time.
After pre-heat, approximately one third of the material in the heating hopper is dispensed into the
vacuum chamber, and the first vacuum cycle begins. Each vacuum cycle has a minimum vacuum time,
set on the Pre-start screen, or the main run screen (VTs). (default is 20 minutes).
The loader loads the Heating Hopper with new material as the Vacuum Chamber receives the heated
material and heating cycle begins concurrent to vacuum cycle (the first vacuum cycle is timed). The new
batch of material in the upper portion of the heating hopper will take less time to heat. Minimum time in
the heating is dictated vacuum time.
After first vacuum cycle, material is then dispensed into retention hopper ready for use. Material in the
retention hopper is blanketed with dry air (if equipped with optional membrane air dryer).
The rate of consumption of dried material from the retention hopper ultimately dictates the amount of
time that the material will be preheated and under vacuum. Examples: If it takes 25 minutes to deplete
the retention hopper, the vacuum cycle will run past its 20 minute setpoint (pre-start screen) to 25
minutes. This is normal operation. However if the retention hopper is depleted in 15 minutes and the
vacuum time is set to 20 minutes, there will be a 5 minute window where no material is available. This
indicates that the throughput of the dryer has been exceeded. If the Throughput Alarm is enabled
(Alarm Setup), a Throughput Alarm (Alarm Code 20) will be triggered.

dryer has been taking offline briefly and powered back on).
At any point during the preheat cycle or standard operation (operation
after initial preheat cycle), pressing the red Shutdown button will bring
up the Shutdown Options screen with the following shutdown options:
Shutdown – Shutdown will continue to run the dryer and process the
material in the Vacuum Chamber and the Retention Hopper until they
are empty. Selecting Planned Shutdown will display the Cooldown
option.
Cooldown (ON/OFF) – When enabled Cooldown will gradually
bring down the temperature of the material in the heating hopper to
the specified temperature (Cooldown Temp) over the specified time
period (Cooldown Time).
To adjust the Cooldown Temperature and Cooldown Time use the
arrow buttons to adjust the setting. Press ENTER to
advance through the digits and to complete the setting adjustment.
Press the Shutdown button to shutdown.
Pressing the red power button during a Planned Shutdown will
display the Immediate Shutdown Screen allowing initiation of an
immediate shutdown of the dryer.
