GETTING STARTED
INSTALLATION
1.
Carefully unpack the controller and inspect it for obvious damage because of
shipping or handling. If the unit appears to be damaged in any way, contact the
Merrick Service Department for assistance.
2.
Mount the controller in your panel, following the instructions on the drawings in
the MC³ Hardware Manual. Make sure there is adequate clearance around the
unit for maintenance and ventilation.
3.
Insure that the Power is disconnected from the Power supply. Make the wiring
connections to the controller, following the instructions on your electrical
connection diagram.
4.
Verify all wiring connections before re-applying power to the unit.
STARTING THE CONTROLLER
Before initially using the controller, you should go through the following steps.
1.
Check all wiring. Normally, a connection drawing is supplied. At a minimum, the
load cells and Power must be connected for the controller to operate. Read more
about inputs and outputs in the MC³ Hardware Manual.
2.
Apply power to the controller. During power up several operations are being
performed. This sequence takes twenty seconds. The start up screen counts
down the time remaining during the start up sequence. Check for any error
messages during the power-up sequence.
Start-up Screen
3.
The controller is normally pre-programmed from the Merrick Factory for your
specific application. A document called the Programming Specification Sheet
(Spec Sheet) is inserted in the last section of the Operator’s manual. The Spec
Sheet contains a record of all parameters.
4.
If the controller has not been programmed, or requires programming changes,
see the Quick Setup (page 11) procedure. Remember to record all changes to
the parameters on the Spec Sheet. Merrick keeps a record of all Spec Sheets in
a database. If you forward the updated Spec Sheet to the Merrick Customer
Support Department, they will update the database.
5.
Choose Set Point method to be used by your application. See Setting the
Setpoint on page15.
6.
Change the Calibration, Diagnostic and Setup passwords to protect your
settings.
Quick Setup
This is a start up procedure to follow when you have to set up a controller that has never
been used before. Following this procedure will overwrite all parameters in the controller.
