Current Settings - P&B MPC2000D Manual

Overvoltage Trip
This setting range 100-120% in steps of 1%, with a default setting of 120% of line voltage determines the pick up
level for the Overvoltage trip function. When the measured voltage reaches this level and is maintained for the
Overvoltage Trip Delay a trip will occur.
Overvoltage Trip Delay
This setting range 1-100 seconds in steps of 1 second, with a default setting of 1 second determines how long an
Overvoltage must be present before a trip will occur.

9.4. Current Settings

Maximum Start Time
This setting with a range of 1 to 250 seconds in steps of 1s. Default Setting 10 seconds determines the time that the
motor is allowed to take to complete it's starting sequence.
Number of Starts
The number of starts the motor will make can be limited by the MPC2000D from anywhere between the range of 1 to
10 in steps of 1, with a default setting of 10.
Start Period
This specifies the time, within which the number of motor starts will be allowed to occur. Should the number of starts
selected be exceeded the motor will be inhibited from starting for a pre-selected time specified by the Start Inhibit
Time value. The Start Period can be between the range of 1 to 60 minutes in steps of 1 minute with a default setting
of 30 minutes.
Start Inhibit Time
This details the time that must elapse before the motor can be restarted after previously exceeding the number of
starts set within the start period. This is adjustable between the range of 1 and 60 minutes in steps of 1 minute, with a
default setting of 15 minutes.
Undercurrent Alarm
If current falls the MPC2000D will sense this and an alarm will be signalled at a set percentage of FLC. This setting
has a range 10 - 90% in steps of 1% of FLC, with a default setting of 50%.
Undercurrent Alarm Delay
Linked to the undercurrent alarm this function can be preset to determine how long an undercurrent below the setting
can occur before an alarm will be signalled. It may be set between the range of 1 and 60 seconds in steps of 1s, with a
default value of 2 seconds.
Undercurrent Trip
This setting specifies below what undercurrent level the unit will trip. It is adjustable between the range of 10 and
90% of FLC in steps of 1%, with a default value of 40% of FLC.
Undercurrent Trip Delay
This sets a time between the unit registering an undercurrent level and the actual tripping of the unit. Adjustable by
the user between the range of 1 and 60 seconds in steps of 1s, with a default setting of 5 seconds.
Load Increase Alarm
Should the load on the motor increase during operation the MPC2000D can sense this and signal an alarm. The pick
up level is adjustable between the range of 60 and 150% of FLC and has a default setting of 120% of FLC, with a
fixed time delay of 5 seconds.
