Table 3-4 lists the default setting for the hold timer attribute. The Hold Attribute for OUT1, OUT2, and
OUT5 is enabled.

OUT3 = 0, OUT4 = 0, OUT5 = 1
Output Logic Override Control
Each output contact can be controlled directly using the select-before-operate output control function. The
virtual output logic expression that normally controls the state of an output contact can be overridden and
the contact pulsed, held open, or held closed. This function is useful for testing purposes. An alarm point
is available in the programmable alarm function for monitoring when the output logic has been overridden.
See Section 6, Reporting and Alarm Functions, Alarms Function, for more information about
programmable alarms. Write access to control functions is required before using the select-before-
operate control functions through the HMI or ASCII command interface. It cannot be achieved using
BESTCOMS.
Enabling Logic Override Control
By default, logic override control is disabled. Output logic override must be enabled before the control can
be used. Enabling of the output logic override control is not possible at the front panel HMI. It can only be
enabled through a communication port using the CS/CO-OUT=ena/dis (control select/control operate-
output override=enable/disable) command. The CS/CO-OUT command only enables or disables override
control of the output logic; it doesn't enable or disable the outputs themselves.
Pulsing an Output Contact
Pulsing BE1-700 outputs provides the same function as the push-to-energize feature of other Basler
Electric solid-state relays. This feature is useful when testing the protection and control system. When
pulsed, an output contact changes from the current state (as determined by the virtual output logic
expression) to the opposite state for 200 milliseconds. After 200 milliseconds, the output contact is
returned automatically to logic control.
