Then press ENTER to enter the specific mode.
Auto Operation:
For functioning in automatic PF correction mode.
Manual Operation:
Pressing ENTER button, while on this screen, will put TPF-56 in Manual
mode. If user has switched to Manual Mode and for 5 minutes no key on
the keypad is pressed, then TPF-56 will automatically switch to Auto
Mode.
In manual mode the user can manually turn ON/OFF the banks. But
this is not allowable for all the faults. In case of the following faults,
turning ON the banks in manual mode is NOT allowed:
1] Under Voltage (UV)
2] Over Voltage (OV)
3] Under Frequency (UF)
4] Over Frequency (OF)
Entry in to Manual Mode of operation first turns-off all the Capacitor
Banks.
This mode is normally used to perform the operations like:
• Resetting of faulty banks to healthy status.
• Checking the Capacitor banks by turning them ON/OFF.
• Declaring specific bank/banks faulty. Masking of the banks so that once
auto mode is selected, these faulty declared banks would not be used for
PF correction.
For Declaring banks faulty or Resetting faulty banks:
While in Manual Mode default screen, press ENTER key.
The cursor above bank 1 will start blinking. Use
keys to select the
specific bank. Then use
key to declare it faulty.
To reset the faulty bank, bring the blinking cursor to that bank and use
key again to declare that bank as healthy.
After any of these operations press ENTER key so that cursor stops
blinking. To save the status on permanent basis (so that even after
Power-down, the status is unchanged), press MEMORY key. After saving
the settings, the unit will jump back to default mode. By default, the
controller is set to operate in AUTO mode.
