Quick Set-Up Via Pc; Rapid Ct Set-Up - ITALFARAD PFC5 Bedienungsanleitung

ITALFARAD S.p .A. via IV novembre n.1 Minerbio (BO) It aly
reactive power demand which is equal to the smallest step (kvar). For higher power
demands, the time will be quicker according to the criteria of inverse proportion.
Example: For 60 s/step, set 060
In this case with the smallest bank of 10kvar (P.02 = 10.0) and a system demanding
20kvar to achieve the set cos ( kvar = 20), the controller will wait for 60/2 = 30 seconds
before beginning the capacitor connection procedure (indicated by the flashing AUT LED).
P.06 LED 1...n Step coefficients
The coefficients of the steps represent the power rating of each step in relation to the
smallest capacitor bank, whose value is programmed at P.02. If a step has the same
power rating of the smallest step, then its coefficient will be 1, while if it is double it will be
2 and so on up to a maximum of 16. By setting 0, the step will be disabled and will never
be considered or used by the controller. The last two steps can be programmed to
operate as normal steps or as alarm relay or again as fan control. If the penultimate step
is linked to a function then the last step cannot be used as a normal step.
To select these functions, press - until the following codes are viewed:
noA = Normally open alarm (contact open in absence of alarm)
ncA = Normally closed alarm (contact closed in absence of alarm)
FAn = Fan control
N.B. For the alarms, see table on page 41. For fan control, refer to pages 36 and 38.
Example: With a PFC7 installed in a control panel with 6 capacitor banks, 5, 10, 20, 20,
20, 20 kvar respectively at rated 460V and the last step is to be used as alarm, the
parameters must be programmed as follows:
P.02 = 5.00 (Smallest step = 5kvar)
P.03 = 460 (Rated voltage 460V)
P.06 LED 1 = 001 (5 kvar = 1 times P.02)
P.06 LED 2 = 002 (10 kvar = 2 times P.02)
P.06 LED 3 = 004 (20 kvar = 4 times P.02)
P.06 LED 4 = 004 (20 kvar = 4 times P.02)
P.06 LED 5 = 004 (20 kvar = 4 times P.02)
P.06 LED 6 = 004 (20 kvar = 4 times P.02)
P.06 LED 7 = noA (Normally open alarm)

1.09 QUICK SET-UP VIA PC

For quick set-up via PC, it is necessary to use the relative automatic test and remote
control software that includes the PC software and the connection cable. For this reason,
all the controller models are provided with a communication port at the rear. All
parameters are displayed on the PC monitor. The settings can be transmitted and stored
with a few simple clicks of the mouse.
If a number of controllers must be programmed with the same settings, the set-up can be
downloaded on a file and reused later by programming all the parameters with maximum
ease and security.
For use of the programming software, see Chapter 2, page 46.
