14. CES circuit breaker opened to remove power 

15. Remove  jumpers and replace leads that were 

changed in steps 7, 8, 9, 10 and 11 above 

16. CES circuit breaker closed to reapply power 

17.  Exit test mode by setting parameter No. 60 to the 

OFF condition from the keypad and display board 

 

An LED located on the keypad and display board 

indicates the test mode.  The test mode is only de-

energized by setting parameter No. 60 to OFF.  The test 

mode is stored in non-volatile memory. 

 

Clutch Test Mode  -  In the test mode, the clutch test 

mode can be entered by setting the clutch test mode 

parameter to ON (parameter No. 61, up arrow (↑)). 

 

The clutch will be engaged full ON with the DMR 

automatically doing the following: 

 

1.  Issuing a clutch ON command 

2.  Setting reference to 100% 

3.  Setting feedback to 0% 

4.  Releasing the DMR inhibit 

 

In the clutch test mode, the clutch is de-energized by 

doing the following: 

 

1.  Setting parameter No. 61 to OFF (down arrow (↓)) 

2.  Exiting the test mode or 

3.  Entering the brake test mode 

 

De-energizing the clutch test mode initiates the following 

sequence: 

 

1.  Reference and feedback are set to 0% 

2.  DMR inhibit is activated 

3.  The clutch ON command is dropped after 450 

milliseconds 

 

Brake Test Mode - In the test mode, the brake test mode 

can be entered by setting the brake test mode parameter 

to ON (parameter No. 62, up arrow (↑)). 

 

The brake will be engaged full ON with the DMR 

automatically doing the following: 

 

1.  Issuing a brake ON command 

2.  Setting reference to 0% 

3.  Setting feedback to 100% 

 

In the brake test mode, the brake is de-energized by 

doing the following: 

 

1.  Setting parameter No. 62 to OFF (down arrow (↓)). 

2.  Exiting the test mode or 

3.  Entering the clutch test mode 

 

De-energizing the brake test mode initiates the following: 

 

1. Reference and feedback are set to 0% 

 

Test Mode Faults - Receiving an enable in the test mode 

will result in an enable in the test mode fault.  Sensing 

press movement in the test mode will initiate a press 

movement in the test mode fault. 

 

VIII.  READY MODE 

The CES controller will be in the ready mode if the 

following conditions exist: 

 

1.  CES control power is applied 

2.  It is not in the run, test or fault modes 

 

The ready mode will be indicated by the "Ready" LED on 

the keypad and display board. 

 

IX. SPEED CONTROL REFERENCE CLAMP 

The CES controller has a maximum speed setting.  If the 

press control sends a speed reference value that is 

greater than this maximum speed to the CES controller, 

the CES controller will clamp the reference at the 

maximum speed.  The “Referenced Clamped" LED will 

light on the keypad and display board, indicating that the 

reference is clamped. 

 

PRESS CONTROL PARAMETERS 

The press control may have constraints on changing of 

speeds and press drive parameters while the press is 

running.  The CES controller will change parameters as 

directed by the press control. 

 

Press control parameters are sent by the press control in 

a packet of bits representing ASCII characters.  The first 

two ASCII characters will be AA.  The packet length is 

68 characters.  Space characters are used to complete 

the 68-character packet.  Upon receiving an EE 

command, the AA packet will be transmitted back to the 

press control by the DMR for comparison to ensure its 

accuracy.  The AA will be changed to EE when sent 

back. 

 

Fault data is sent by the CES controller upon request of 

the press control.  The two ASCII characters of the 

"Request to Send Fault Data" will be BB.  The packet 

length of the request will be two characters.  The DMR 

will send the fault data in a packet of bits representing 

ASCII characters.  The first two ASCII characters will be 

BB.  The remaining characters will be four-digit numbers,
