SECTION 9 – PRESS CONTROL OPERATION -- WIRED INTERFACE
9.1 CONTROL INPUT SIGNALS
The EC-2000-CES controller will accept nine different input command signals from the press controller
that are available for the operator to make, they are as follows: two Enables, Clutch Contactor ON, Inch,
Micro Inch, Reverse, Control Power ON, Stop-On-Top and Fault Reset. Some controls also have a Stop-
on-bottom command.

ENABLES:
The enable signals are required to start the drive. These contacts are the last contact closures in
the start sequence. The clutch contactor ON signal and the two enable signals must all be given
within the time set in parameter H.2 of one another or a fault will be created. The enable contacts
must be closed in order to run. Upon opening either of these contacts, the press control signals
the controller to stop the drive immediately with
a command to zero speed and to open the clutch
contactor in the programmed time delay in parameter D.10. The controller responds to this
removal of enable with a normal stop signal output signal. The enable contact closures must be
given only after all safety features of press operation have been determined to be in a "GO"
status by the press control. Red/- inputs are provided to ensure that the enable signal is
present and that the receiver is not shorted. The enable signals consist of two press control
contact closures that put the 115 VAC of the press control into the I/O board. Enable High places
120VAC on the brake control board input and Enable Low ties the input to AC common.

CLUTCH ON (INPUT):
In addition to the enables, the press control provides 115 VAC to energize the clutch contactor.
This ensures that the press control has absolute control over the ability of the CES controller to
energize the clutch. This input signal monitors the 115 VAC signal. The clutch contactor ON
signal is one of the signals that activate the control command which closes the clutch contactor
and sends a speed command to the controller .

INCH:
The inch signal indicates that the controller is directed to operate at inch speed. The two enables
and clutch on signal are need as well. The inch command can only be changed when the enable
command is not present; otherwise, a fault will be generated. The inch signal consists of a press
control contact closure that puts the 115 VAC of the press control into the brake control board.
