The No-Volt trigger is intended for the use as a fast setpoint override condition for PFC operations in order to protect the capacitor banks against voltage interruptions. When used with the Hard Switch-Off action, it can de-energize the output relays in approximately 25 ms. This avoids bringing the still charged capacitors back after the voltage is restored. When used with other setpoint actions, this trigger can provide the response time to alarm conditions at 25-75 ms.

4. The target power factor limits are always specified for the I and IV quadrants regardless of the location of the instrument on the source or load side. The PFC will automatically account for the direction of power flow providing full four-quadrant operation. 5. If both target power factor limits are specified for the same quadrant, the high power factor limit should never be less than the low limit.

Chapter 5 PFC Setup and Operation 5. PFC Setup and Operation This chapter describes how to setup the Power Factor Controller for your application and explains its important features. Brief instructions are included for certain setup and display operations. Complete setup instructions are found in Section 4.13, PFC Setup; complete display information is found in Chapter 6 (Data Display) and Chapter 7 (Viewing Status Information). 5.
To specify the bank as a permanently switched bank, set the bank size parameter to On (see Section 4.13, PFC Setup). The permanently switched banks are switched in automatically when the PFC is put into either manual or automatic operation mode and before a switching program begins, and are switched out when the PFC shuts down, following all switching and re-connection time delays.
the target. When no leading (capacitive) target power factor is allowed, only combinations that provide lagging (inductive) power factor will be checked. The banks are connected and disconnected starting from the low-size banks, following all pre-set switching and re-connection delays. Alternation of switching operations is provided when needed to avoid excessive deviation from the target power factor. The optimization program is complete when one of the following is true: 1.
Shutting the PFC Down From the PFC setup menu, set the PFC operation mode to OFF. This will put the PFC into Shut Down mode. Shut Down mode provides step-by-step disconnection of all the capacitor banks that are under the PFC control. The banks switch out progressively, following disconnection intervals (switch-off delays). After all the banks are switched out, the PFC is put into OFF state. 5.2.
PFC will not take into account the status of the digital input. The second setpoint will not even appear in the PFC setup menu. If you want to use different target setpoints and switch them depending on the time schedule or another external condition, specify the operational setpoints as SP1-2. In this event, both SP1 and SP2 setpoint ranges will be available for setup, and should be defined for proper operation.
defined setpoint operate delay. This makes the trigger less sensitive to fast changes in load thus avoiding excess switching. The operate delay timer is reloaded each time the measured power factor oversteps the setpoint range limits. The allowable range for the operate delay is 1 to 3600 sec. The default value is 3 sec. Low Lacking Reactive Power To avoid excess cycling, the power factor setpoint will not trigger the PFC if the lacking reactive power is less than 0.
Normally, the capacitors discharge through fixed resistors that are connected to the capacitors directly or via auxiliary contacts of the contactors. Refer to the capacitor data sheet for the recommended discharge time for your capacitors. The re-connection delay can be adjusted in the range of 3 to 3600 sec. The default setting is 300 sec. 5.2.
The C192PF8-RPR allows you to choose between manual and automatic adjustment of the capacitor bank powers.
5.3 Capacitor Banks Protection 5.3.1 PFC Protective Actions The reason for the PFC protection mechanism is to protect the capacitor banks and contactors against harmful conditions that would lead to extremely high overvoltage, or would cause undesirable effects such as high transient voltages and currents and high harmonics.
5.3.2 PFC Protection Setpoints Protection against Voltage Interruptions The fast disconnection of the capacitor banks is required in the event of shortterm voltage interruptions that would cause damage to the still-charged capacitors when the voltage is restored. The No-Volt alarm override condition (see Table 4.6) along with the Hard SwitchOff action can de-energize the output relays in approximately 25 ms whenever voltage interruption is detected.
Protection against High Harmonics High THD protection prevents damage to capacitors at high levels of voltage harmonics, which can be caused by voltage resonance at a higher frequency. The effect of the high THD setpoint protection is limited progressive disconnection of the capacitor banks until resonance conditions disappear, and then, after a long safety delay, returning the PFC into normal operation. The setpoint can operate at high THD of 3 to 300% depending on the network conditions with a delay of 0.
Chapter 6 Data Display 6. 6.1 Navigating in the Display Mode The front panel has a simple interface that allows you to display numerous measurement parameters in up to 43 display pages. For easier reading, the parameters are divided into three groups, each accessible by a designated key.
Alarm/Man Mode LED This LED has two functions. The blinking LED indicates that the PFC is operating in Manual Mode. The constantly lit LED gives you an alarm indication.
