Basler Electric BE1-700 - Manual (Page 50)

Pulse override control is accessed at Screen 2.4.1 of the HMI by entering a P in the field for the output
contact to be pulsed. Pulse control is accessed through a communication port by using the CS/CO-
OUTn=P (control select/control operate-output contact n=pulse) command.
Holding an Output Contact Open or Closed
Outputs can be forced to a closed (logic 1 or TRUE) state or to an open (logic 0 or FALSE) state. This
feature can be used to disable a contact during testing. Open or close logic override control is accessed
at Screen 2.4.1 of the HMI by entering a 0 for open or 1 for closed in the field for the output contact to be
controlled. Outputs are forced open or closed through a communication port by using the CS/CO-
OUTn=P0/1 (control select/control operate-output contact n-0/1) command.
Returning an Output Contact to Logic Control
When the output logic has been overridden and the contact is held in an open or closed state, it is
necessary to manually return the output to logic control. Outputs are returned to logic control through
Screen 2.4.1 of the HMI. An L is entered in the field of the contact that is to be returned to logic control.
Outputs are returned to logic control through a communication port by using the CS/CO-OUTn=L (control
select/control operate-output contact n=logic control) command.
The output control commands require the use of select-before-operate logic. First, the command must be
selected using the CS-OUT command. After the command is selected, there is a 30 second window
during which the CO-OUT control command can be entered. The control selected and operation selected
syntax must match exactly or the command will be blocked. If the operate command isn't entered within
30 seconds of the select command, the operate command will be blocked. An error message is returned
when a control command is blocked.
Output control commands are acted on immediately except when the ENA and DIS modes are used. ENA
and DIS output control command changes aren't executed until saved with the EXIT command. Output
control status is saved in nonvolatile memory and is maintained when relay operating power is lost. All
relay responses in the following examples and throughout the manual are printed in Courier New
typeface.
CS/CO-OUT Command Examples:
1. Enable the output control feature.
>CS-OUT=ENA
OUT=ENA SELECTED
>CO-OUT=ENA
OUT=ENA EXECUTED
>E (exit)
Save Changes (Y/N/C)?
>Y (yes)
2. Test all outputs by pulsing momentarily.
>CS-OUT=P
OUT=P SELECTED
>CO-OUT=P
OUT=P EXECUTED
3. Disable the trip output (OUT1) by holding it at logic 0.
>CS-OUT1=0
OUT1=0 SELECTED
>CO-OUT1=0
OUT1=0 EXECUTED
4. Return OUT1 to logic control.
>CS-OUT1=L
OUT1=L SELECTED
>CO-OUT1=0
OUT1=L EXECUTED
