Voltage Settings; Current Settings - P&B Goldstart MPC2000 Manual

9.3. Voltage Settings

Undervoltage Setting
This setting range 50-95% in steps of 1% with default setting of 80% of line voltage determines the pick up level of the
Undervoltage protection. When the measured voltages reaches this level for the period equal to the Undervoltage
Delay period a trip will be performed, unless the Undervoltage Restart feature is selected.
Undervoltage Delay
This setting range 0.2-10 seconds in steps of 0.1s with a default setting of 5s determines how long an Undervoltage
condition must be, before a trip occurs.
Undervoltage Restart
This setting range 'Yes' or 'No' with default setting of 'No' allows the MPC2000 to monitors the Power Supply
(Terminals 61 & 62) and detect short voltage outages to provide automatic restart facilities. When set to 'Yes" , on
detection of a voltage dip or loss the MPC2000 will maintain the starting signal to the contactor for 200 msec at which
time the motor will be stopped. If the voltage is then restored within 4 seconds the MPC2000 will restart the motor after
the preset time delay. If the voltage does not return within 4 seconds the motor will not be restarted.
Undervoltage Restart Delay
This setting range 0.2-120 seconds in steps of 0.1s upto 10s and 1 sec above is available if the above is set to 'Yes',
determines the delay before an automatic restart is performed.
Overvoltage Alarm
This setting range 100-120% in steps of 1%, with a default setting of 115% of line voltage determines the pick up
voltage for the Overvoltage alarm function. When the measured voltage reaches this level and remains for 1 second an
alarm will occur.
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 MPC2000 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.
