Protective Trip and Warning Functions Chapter 3
• Starts Counter parameter is equal to or greater than the value set in the PM
- # Starts parameter
Upon a PM - # Starts warning, the following will occur:
• The TRIP/WARN LED will flash an amber 14-blink pattern
• Bit 13 in Parameter 15, Warning Status, will go to “1”
• Bit 1 in Parameter 21, Device Status, will go to “1”
Parameter 101, PM - # Starts, allows the installer to set a number of starts. It is
adjustable from 0…65,535.
The EC4 Current Monitoring Relay will give a PM – Oper. Hours warning
indication when:
• PM – Oper. Hours warning is enabled
• Elapsed Time parameter is equal to or greater than the value set in the PM
– Oper. Hours parameter
Upon a PM – Oper. Hours warning, the following will occur:
• The TRIP/WARN LED will flash an amber 15-blink pattern
• Bit 14 in Parameter 15, Warning Status, will go to “1”
• Bit 1 in Parameter 21, Device Status, will go to “1”
Parameter 102, PM – Oper. Hours, allows the installer to set a number of hours of
operation. It is adjustable from 0…65,565 hours.
Queue Clearing
The EC4 Current Monitoring Relay provides the capability to clear the Trip Logs,
Warning Logs, Starts Counter, and the Elapsed Time using the Clear Queue parameter. If
using the Preventative Maintenance Flags, the user will want to reset the
Starts Count and
Elapsed Time after preventative maintenance has been performed.
Parameter 104, Clear Queue, allows the user to clear the Trip Logs (parameters 16…20),
Warning Logs (parameters 90…94), Starts Counter (parameter 96), and the Elapsed Time
(parameter 95). The Clear Queue parameter will clear/reset all of these parameters at the
same time.
