External Alarm Trip
The user has the option of having four external alarm inputs (Alarm 1 through Alarm 4)
“trip” or “not trip” the RK3000 control. A trip alarm results in the IGBTs shutting off, the
alarm relay closing, an alarm message appearing in the Device Status Screen, and the
control cabinet contactor de-energizing. A non-trip alarm closes an alarm relay and
displays an alarm message in the Device Status Screen, but the control continues to run.
When a non-trip alarm occurs, the alarm relay remains closed as long as the alarm is
active. If the alarm condition clears, the alarm relay is opened to indicate an alarm
condition is no longer present. The alarm line in the Device Status Screen will continue to
display the alarm until it is manually cleared by pressing the CLEAR ALARM key.
Press the PROMPT key and then the DOWN
key until the “External Alarm Trip” Prompt
Screen appears.
Press ENTER and the ‘External Alarm Trip” Parameter Screen will appear.
To trip the control for an external alarm condition on the Alarm 1 input, press the 1 key.
To just alarm for an external alarm condition on the Alarm 1 input, press the 0 key. Your
selection will appear opposite the word Enter, and become active when the ENTER key is
pressed.
