Location of terminals (view of case rear side)
Wiring recommendationsThe input network may carry significant parasites, and they may disturb the complete processing chain. In order to avoid this, the immunity from disturbances can be made significantly better by respecting a few simple rules : - do not connect too close : the input network and the Peca 5 power supply wires,- do not connect too close : the inut network and all the Peca 5 output wires,- use for all Peca 5 outputs shielded cables connected to the GND on both ends.
To avoid any influence of the current intake on the voltage measurement, connect CTs before VTs.
Network LoadS1!INPUTS
Respect correct wiring : S1 corresponds to P1, S2 corresponds to P2. The CT and VT S2 secondaries must be connected to the earth. Connect this point to terminal 2 on the instrument.!

Note for the entering of the Pri.tc and Pri.tP :The instrument will always try to display with the highest resolution.eg. : for Pri.tP = 400.0, the display will befor Pri.tP = 0400, the instrument will save the value Pri.tP = 400.0 and we will have the same display in measurelikewise for Pri.tc = 0010, the instrument will save Pri.tc = 10.00 and in measure we will have as display
The decimal point position is set once and for all on the configuration saving (taking into account the display with the highest possible reso-lution). It may in no case be modified in measure, that is to say after a display of , if the input signal carries on increasing you will have (display overstepping), and not with moving of the decimal point to the right.Beware : By pressing and you can change the display resolu-tion if you do not want to have a maximum resolution (see p18).

COS
4.5.8 Programming of the cosine The cosine sign will indicate the direction of the current (receiver or generator). The cosine sign will indicate the nature of the load (capacitive or inductive).Example : Say a cos=0,85;For an electrical cos, the display will be L0.85 or C0.85 (according to the nature of the load).For a mathematical cos, the display will be -0.85 or +0.85 (according to the direction of the current and the mode : generator or receiver).In the case of an electrical cosine, the choice will be between an electri-cal cosine centered on 0 or on -1/+1. Centered on 0 Centered on -1/+1

• Mathematical cosine :the cosine sign will indicate the direction of the current (receiving or generating).Eg. : The load can be either current receiving or generating. A cosine between -0.5 and +0.5 is transmitted on a 4-20mA output.

• Electrical cosine centered on 0:the cosine sign will indicate the nature of the load (capacitive or induc-tive)Eg. : a network is measured with a cosine compensation by capacitors. The nature of the load is inductive, but if you compensate too much you may obtain a capacitive load. The cosine will oscillate around -1/+1. A 4-20mA output is programmed for a cosine between -1 and +1.
• Electrical cosine centered on -1/+1:Eg. : taking prevous example again, the 4-20mA output is programmed for a cosine between -0.5 and +0.5.
The cosine oscillates around -1/+1. The current output gives jumps from 4 to 20mA. The use of a viewmeter is impos-sible, but the linear transfer function allows the use of a digital panel meter on the current output.To avoid the jumps from 4 to 20mA, use following configuration :
+20mA
12mA
-1 -0.5 +0.50 +1+4mA p12

p13
When the cosine oscillates around -1/+1, the current output remains around 12mA. The unlinear transfer function does not allow the use of a digital panel meter on the current output.

As measure reverts below the alarm setpoint, the relay remains on and the led blinks to warn the user that a setpoint has been passed (to reset the recording of alarms to zero see menu p 16).Note : An exit from mode programming with configuration saving will reset the recording of the alarms to zero. • Display of the alarm messagesA programmed alarm message can be made to appear alternating with the measure. The message will appear only during the alarm, while the associated led is lit.• Setting of the setpoints : There are 2 ways to adjust setpoints.- either in mode programming entering the correct access code - either by pressing simultaneously on and if the access to a quick entering has been authorized on the code programming (see p.18). b) Mode pulses weight of the pulse (decimal point + unit)Width of the pulses : 400 ms.Maximum count rate : 1 pulse / second

(Accessible according to the programmed access code)
The automatic voltage or current cut off setting is an operation that will enforce the voltage or current to 0 for U (I) low values. Once the menu is chosen, the instrument will measure the values on its inputs and enforce display to 0 for values lower than the programmed cut-off in percentage of the full scale. To eliminate these cut-offs, just go into programming and programme a new cut-off value (current from 1.0% to 15% in manual caliber, from 0.2% to 15% of caliber 5A in auto caliber, voltage from 1.0% to 20% in manual caliber, from 0.3% to 20% of cali-ber 500V in auto caliber).
