SAFETY First!
This symbol is used throughout this Manual to identify particular stages where the
bin Contractor and/or Operator need to take special note and precautions regarding
the danger described in these Instructions. Please read all the SAFETY information
and the instructions completely prior to beginning the construction.
Recognize and Understand SAFETY Information
This is the Safety-Alert Symbol. When you see this symbol on your equipment or in
this Manual, be alert to the potential for personal injury. It may be used alone or in
conjunction with a signal word. Signal words DANGER, WARNING, or
CAUTION, are used with the Safety-Alert Symbol. Be sure to follow ALL national,
state and local safety standards governing each installation site.
DANGER! Electricity can KILL! All electrical installations and testing MUST be done by a
QUALIFIED and properly certified/licensed ELECTRICIAN, in accordance with
all applicable national, state/provincial and local codes. Brock Grain Systems
neither will be liable for damage to the Dryer or to person(s) because of
unqualified electrical testing, installation or use. Improper procedures willvoid
the Warranty. Failure to follow these instructions will create an imminently
hazardous situation which, if not avoided, will result in serious injury that
could lead to death. See the chapter on Electrical Installations.
IMPORTANT! It is the responsibility of the Contractor, Installer, Owner and Operator to
supplement the Dryer furnished by Brock Grain Systems with any necessary
ELECTRICAL or STRUCTURAL items to make the Dryer installation comply
with the National Electric Code, National Electric Safety Code, and OSHA
(U.S.); the Canadian Electrical Code (Canada); and any other applicable
federal, state and local laws and ordinances.
SAFE Electrical Installations
Think SAFETY!
Work SAFELY!
Symbol Description
DANGER is a signal word that indicates an imminently hazardous
situation which, if not avoided, WILL result in death or serious injury.
WARNING is a signal word that indicates a potentially hazardous situation
which, if not avoided, COULD result in death or serious injur y.
CAUTION is a signal word that indicates a hazardous situation which,
if not avoided, MAY result in minor or moderate injury.
IMPORTANT indicates vital information or instructions, highly
recommended and/or pertinent, for the safe installation or operation
of your equipment. It may have a pictogram to indicate mandatory
equipment (i.e., PPE) or action (i.e., grounding, read the manual).
This is the International PROHIBITION Sign, or NO Sign, which indicates
something (i.e. smoking) is not permitted.
This internationally recognized HAZARD symbol is customized with
a pictogram showing the general type of DANGER.

Qualified Electrical Personnel ONLY!
WARNING! Procedures in this Manual are intended for use by qualified electricians ONLY!
Failure by qualified electrical installers to read and/or understand the contents
of this Manual, and/or the failure to follow proper procedures outlined in this
Manual—BEFORE Dryer testing and startup—constitutes a misuse of the
equipment and an unsafe situation that could result in death or serious injury,
and/or could damage the equipment and void the Warranty.
This Manual contains diagrams and basic steps to provide the qualified electrical
Installer with information for a safe installation. Due to the customized design of the
BROCK® MEYER® Dryer some electrical installation remains at the Installer’s
discretion according to all applicable federal, provincial/state and local laws and
codes. Follow recommended precautions and safe operating practices of national and
local codes at each installation site.
IMPORTANT! It is the responsibility of the Contractor, Installer, Owner and Operator to
supplement the Dryer furnished by Brock Grain Systems with any necessary
ELECTRICAL or STRUCTURAL items to make the Dryer installation comply
with the National Electric Code, National Electric Safety Code, and OSHA
(U.S.); the Canadian Electrical Code (Canada); and any other applicable
federal, state and local laws and ordinances.
Always use properly rated/insulated PPE when working near sources of electricity
and other hazards. Installation is not complete until a SAFETYSystems checkout is
run to see that all SAFETY systems are in working order. This must be done before
initial startup. It should also be done at the beginning of each season, and any
components replaced if necessary.

BROCK® MEYER® Schematics Intui-DRY® Controller: the Brain of the Dryer
MFH1968-3G 5
Manual MFH2191 is necessary for installing the Intui-DRY® Controller.
The Installer will need schematic drawings 3924-00001, 3924-00031 and 3924-
00033 (Block-and-Bleed) to install the Intui-DRY Controller on the MEYER®
Dryer. Those are included in the back of this Manual and in the Intui-DRY Manual.
Other than factory-approved software options or upgrades described in the Manual,
no other equipment or devices are to be mounted or installed inside the red
Control Cabinet. All auxiliary equipment (contactors, relays, motors, etc.) must be
mounted separately in the red MEYER® Power Cabinet.

BROCK® MEYER® Schematics Allen-Bradley Power Flex 525 Fault Code Descriptions
MFH1968-3G 15
Allen-Bradley Power Flex 525 Fault Code Descriptions
Fault Types, Descriptions and Actions
No. Fault Type (1)
Description Action
F000 No Fault No fault present.
F002 Auxiliary Input 1 External trip (Auxiliary) input. • Check remote wiring. • Verify communications
programming to intentional fault.
F003 Power Loss 2
Single-phase operation
detected with excessive load.
• Monitor the incoming AC line for incoming
voltage or line power interruption.
• Check input fuses.
• Reduce load.
F004 UnderVoltage 1
DC bus voltage fell below
the minimum value. Monitor the incoming AC line for low voltage or line power interruption.
F005 OverVoltage 1
DC bus voltage exceeded
maximum value.
Monitor the AC line for high line voltage or
transient conditions. Bus overvoltage can also
be caused by motor regeneration. Extend the
decel time or install dynamic brake option.
F006 Motor Stalled 1
Drive is unable to accelerate or
decelerate motor.
• Increase P041, A442, A444, A446
[Accel Time x] or reduce load so drive output
current does not exceed the current set by param-
eter A484, A485 [Current Limit x] for too long.
• Check for overhauling load.
F007 Motor Overload 1
Internal electronic overload
trip.
• An excessive motor load exists.
Reduce load so drive output current
does not exceed the current set by
parameter P033 [Motor OL Current].
• VerifyA530 [Boost Select] setting.
F008 Heatsink OverTmp 1
Heatsink/Power Module
temperature exceeds a
prefedined value.
• Check for blocked or dirty heat sink fins.
Verify that ambient temperature has not
exceeded the rated ambient temperature.
• Check fan.
F009 CC OverTmp 1
Control Module temperature
exceeds a prefedined value
• Check product ambient temperature.
• Check for airflow obstruction.
• Check for dirt or debris.
• Check fan.
F012 HW OverCurrent 2
The Drive output current has
exceeded the hardware
current limit.
Check programming. Check for excess load,
improper A530 [Boost Select] setting, DC brake
volts set too high or other causes of excess current.
F013 Ground Fault 2
A current path to earth ground
has been detected at one or
more of the drive
output terminals.
Check the motor and external wiring to the
drive output terminals for a grounded condition.
F015 Load Loss 2
The output torque current is
below the value programmed in
A490 [Load Loss Level] for a
time period greater than the
time programmed in A491
[Load Loss Time].
• Verify connections between motor and load.
• Verify level and time requirements
F021 Output Ph Loss 2
Output Phase Loss (if enabled).
Configure with A557 [Out
Phas Loss En].
• Verify motor wiring.
• Verify motor.
F029 Analog In Loss 1
An analog input is configured
to fault on signal loss. A signal
loss has occurred. Configure
