2.0 PRINCIPLE OF OPERATION
Novatec MCS-405A CONTROLLERS are designed to operate a single vacuum power
unit to convey material to a maximum of six stations. Each vacuum receiver may be
turned on individually with its separate ON/OFF switch. It will sequentially load each
station that needs material and skip each station that is full. The MCS-405A does not
include Blowback nor a NO-LOAD alarm.
This controller cannot control proportioning, but an additional control box (PC-1) can be
added to each station where proportioning is required. Proportional valves are capable
of providing a layering or blending effect to the materials conveyed. In addition, the PC-
1 adds Blowback capability to the stations so equipped.
3.0 UNPACKING AND INSPECTION
The MCS-405A controller is shipped complete and is fully programmed from the
factory. After receipt of the unit, completely inspect it for damage. Although, the units
are packaged securely, vibration and mishandling during transit can cause damage. All
screws, bolts and other connections should be checked to make sure they have not
come loose in transit. Report any damage immediately to the transportation company.
4.0 INSTALLATION
4.1 General
The single most important activity performed to ensure satisfactory operation of
a pneumatic convey system is the actual installation of the equipment, with
personnel safety weighted at every decision point. All components should be
located so that material lines and vacuum lines are as short as possible. Elbows
or other changes in direction are minimized. The material conveying line should
be horizontal and/or vertical and as direct as possible with no slope. Care needs
to be taken that all connectors are vacuum tight. All rigid conveying tubing should
be properly supported by the user to provide a safe, but secure installation. It's
generally acceptable to use flexible hose and clamps to connect material pick up
lances, vacuum chambers, etc., to material or vacuum lines. The flexible hose
should be only as long as needed since excess hose will reduce the efficiency of
the system. The hose should not sag. The conveying lines should be grounded
to prevent "shocks" from static electricity that may be generated by some
materials as they are conveyed.
Rigid tubes and elbows should be connected together with bolted couplers. Each
tube end should be square cut, round, and without burrs. The tube ends should
butt together when installed, with the bolted coupler centered over the joint.
All national and local codes need to be followed. Proper grounding of all
equipment is important. Check the electrical wiring schematic for wiring numbers
and details. The following describes installation of typical system components.

4.2 Vacuum Power Unit
Locate so that access to the secondary filter element
mounted to the vacuum power unit is available. Secure
to floor or platform as necessary. Attach high voltage
(check nameplate) to the motor starter (located in the
motor starter junction box mounted to the vacuum power
unit) from a field supplied disconnect switch or to the
optional combination starter with fused disconnect
switch. An electrical ground wire is also required. A
clean, dry supply of 80-120 PSIG compressed air is
connected to the vacuum breaker valve solenoid. When
the vacuum breaker valve is energized it allows ambient
air to pass through the vacuum blower. This is done
instead of simply shutting the pump down to prevent premature wearing of the
pump and belt drive caused by constantly starting and stopping the pump.
Eventually the pump will shut down completely if not needed when the search
timer expires.
4.3 Station Valve
Some vacuum receivers have a built-in station valve.
Otherwise, locate a separate station-T conveniently to
each vacuum receiver. Typically the station-T valve is
rigidly attached with bolted couplers to vacuum lines
running to the vacuum power unit or to the optional
cyclone filter while flex hose is used to connect the
vacuum inlet to the top of the vacuum chamber. The
station valve solenoid is wired to the main control
panel. Ground the system as necessary. A clean, dry
supply of 80-120 PSIG compressed air is connected to
the station tee valve solenoid.
4.4 Cyclone Filter
Locate the cyclone filter as close as possible to the vacuum power
unit. Provide access for the material with catch pan or fines drum as
necessary. Secure the cyclone filter to the floor or platform. Attach
vacuum lines from the conveying system to the cyclone inlet
(Tangential inlet on the side of the cyclone body). Attach the cyclone
outlet (top duct) to the vacuum breaker valve inlet on the vacuum
power unit.

6.0 OPERATION
6.1 General
Push the SYSTEM switch to the "ON" position. Enable the desired stations by
switching the individual ON/OFF STATION switches to the “ON” position. The
vacuum power unit motor will then start and load material to the first empty
station for a time that is adjustable by changing the Load Time value in the
“SETTINGS” menu of the controller. The load time may be increased or
decreased as necessary. See “CHANGING PARAMETERS” on page 8 of this
manual.
NOTE: DO NOT ALLOW RECEIVER TO OVERFILL.
When the load time is completed, the
controller will select the next station
that is enabled and needs material,
allowing material in the first loaded
vacuum receiver to fall through the
dump valve. The dump time begins
at the end of the load time and may
be adjusted as necessary. The dump
value should be set 1 to 2 seconds
greater than the time necessary for
the chamber to completely empty.
The load and dump cycles will
continue until all the drying hoppers
or surge bins are full, at which time
the material will hold the dump valve
flapper open, placing the system in a
“Seek-time” mode. If the hoppers
remain full until the end of the search
time, the pump will shut down. As
material is withdrawn from the hopper, the material level will fall, the flapper will
close, and the loader will again activate to automatically keep the hopper full.
On machine mount units the load and dump cycles will continue if the material
level remains below the sensors located on the sight tube. When the material is
above this point a capacitance sensor or a pair of photoelectric sensors will
continuously detect material and not allow the system to load. As material is
withdrawn, the level will fall, and the sensors will no longer detect material. The
loader will then continue with the loading cycle.

7.0 PARAMETERS EXPLANATION

© 2018 Novatec, Inc All Rights Reserved 10
MCS-405A IM 13 OCT 2018
7.1 Load Time: Pmp/LT
Measured in seconds, this is the amount of time the vacuum pump will run to
load material into the vacuum receiver. Too little time will result in insufficient
loading. Too much time will pack the loader full of material, prematurely blinding
the filter and possibly clogging the conveying line. This setting should be
adjusted over the course of several normal loading cycles to ‘just fill’ (but not
overfill) the vacuum receiver. NOTE: VRP series powder receivers include an
extended body to house the cartridge filter(s). Loaded material should not be
allowed to be filled up into this extended hopper area. It is intended only as a
housing for the filter cartridges(s), not a hopper for collecting loaded material.
NOTE: DO NOT ALLOW VACUUM RECEIVER TO OVERFILL.
7.2 Dump Time: Pmp/DT
Measured in seconds, this is the setting for how long the loader will remain at rest after
loading, to allow material to evacuate the loader. This setting may be increased in case
the material is very slow moving.
7.3 Seek Time: Pmp/ST
Also measured in seconds, this parameter controls how long the vacuum pump will seek
for a call for loading before the vacuum breaker valve is activated, allowing ambient air to
pass through instead of shutting down, which causes undue wear.
8.0 SETTING THE TIME
The following describes how to set the internal clock. This clock is for reference only and has no
effect on the operation or function of the controller. The controller does not have a battery to
maintain the time when power is off. Instead it uses a capacitor that has reserve power for 80
hours. If power is off for a longer period of time, the clock will need to be reset.
9.0 RUNNING HOUR COUNTER
It is advantageous to know how many hours your vacuum system has been running so you know
when maintenance is required. The MCS-405Aallowyoutokeeptrackofthosehoursautomatically.
The running hours of the vacuum pump (whenever the pump is energized) are counted and
displayed in the lower right hand corner of the MSC-405A display on the home screen.
