INSTALLATION AND START-UP

The manual you hold in your hand contains information and warnings that the user should respect in order to guarantee a proper operation of all the instrument functions and keep its safety conditions. The instrument must not be powered on and used until its definitive assembly on the cabinet’s door.

If the instrument is not used as manufacturer’s specifications, the protection of the instrument will be damaged. When any protection failure is suspected to exist (for example, it presents external visible damages),the instrument must be immediately powered off. In this case contact a qualified service representative.

Installation

Mounting

• Instrument is to be mounted on panel (cut-out 112.5112.5+0.8 x 112.5112.5+0.8 mm). All connections keep inside the cabinet.

Voltage input

• Input voltage should not exceed the rated input voltage products ( please confirm it before your order), the input voltage to be installed in the 1A fuse.

Current Input

The standard input current is 5A, if greater than 5A should use external CT. Even if you are using on the CT are connecting with other instruments, wiring methods should be used in series Before remove the current input connection, must be sure to disconnect the primary circuit or shorted secondary circuit of CT. Suggest using the terminal block, please not directly connect to CT, in order to facilitate disassembly.

Notes

1. In setting/test mode, if 15 seconds without action, the controller will return to automatic control mode.
2. If the controller s how ‘UAC UBC UAB” to indicate the wiring method is 3P3W show’ IA IB IC ‘ to indicate the wiring method is 3P4W.
3. shows the current power factor, if the current power factor greater than 0.5, and does not advance , go to next step
   • If the current power factor less than 0.5 or advanced , then that connection error current signal and voltage signals are in phase , circular display ‘ or ‘ or ‘ if it is satisfied the re is no connection error , that is, that the current grid True power factor ofless than 0.5 , hold down the button to confirm can enter the next step

Workflow description

1. Power on and reset, the LED screen all on , show 888
2. Controller automatic test voltage and current signals:
   • Show ” noU “, mean no voltage signal (see troubleshooting for solution)
   • Show ” noI “, mean no current signal (see troubleshooting for solution)
3. Automatically determine the terminal connection mode:
   • If the controller show UAC UBC UAB to indicate the wiring method is 3P3W show “ IA IB IC to indicate the wiring method is 3P4W.
   • If the current power factor less than 0.5 or advanced , controller judge as connection error , the display show Err ” mean that wiring is incorrect
   • After diagnos is by artificial , eliminate wiring errors , user can press to skip the check
4. Then press to set the control parameter ( Details please refer to C hapter 7.1
   • controller detects and displays the current grid power factor, when the power factor is under the lower limit set, controller automatically connect capacitor until the power factor between the lower and 1.00.
   • When the power factor over the 1.00 , the controller automatically removed capacitor until the power factor in the set range.
   • When the load current is less than the set under current value, the controller running in l ock method , without any action to protect the capacitor
   • When the grid voltage exceeds the over voltage setting value, the controller automatically cut off all capacitor
