UNS0122A-P 3BHE042393R0101 Pulse output module

Process Units 

• Allows user to configure Process Input values to be displayed in other units besides milliamps or voltage. o The KW Transducer signal will still be in milliamps or volts. 

• This selection effects Process Configurations: o Process Reference o Process High Limit o Process Low Limit o Process High Value o Process Low Value 

• Status screens effected o Discrete I/O o KW Load

Check Mains Breaker • Used to activate checking of mains C.B. Aux. Discrete input when enabled. 

• If disabled, unit relies on other units with this set point enabled to broadcast state of mains C.B. Aux. contact over network. 

• Units Controlling Mains Breaker must have Check Mains Breaker Enabled.

Fast Transfer Delay 

• Time required for a transition in switching from Mains to Generator operations, and from Generator to Mains operations.

 • Critical for Open Transfer applications. 

• The transition time between Bus and Mains sensing is 1.2 seconds. o With the Fast Transfer Delay set for 0.1 seconds, the transfer will take 1.3 seconds. Mains Stable Delay

 • Period of time required for the mains to be declared stable (within voltage and frequency limits for the specified time) before transition from generator(s) to mains. Generator Stable Delay 

• Period of time generator must be declared stable (within voltage and frequency limits for the specified time) before transition from Mains to Generator, as well as dead bus closing.

Load Surge 

• Used only in Base Load or Process Control. (Mains Parallel Operations)

 • Set to trigger at a percent of total generator load shift per second while operating in Mains Parallel. (% Rated Load/Second) 

• Can be set for Loss of Mains Detection. 

• Instantaneous Trigger. Load Surge Alarm The load surge condition will cause a response defined by this set point. 

The available responses are:

 • Disabled • Warning 

• Loss of Mains 

• Loss of Mains with Alarms Main Volt High Limit 

• Alarms when Mains Voltage exceeds Alarm Set Point. 

• Alarm can be set for Loss of Mains.

 • If Mains Voltage is above High Limit, Mains are not considered stable, and the EGCP-2 control will not issue a mains breaker closure command.
