Pleae advise on the easiest connection cables and comms set up of the following.
Software is RS Logix 500 V5.20.00, RS Linx, PanelBuilder 32 V 3.80.00.
PC is old, runs on win ME with a 9pin RS232 port.
PLC is one year old Micrologix 1200.
I need to connect a AB 550T HMI to the PLC and also...
Thanks to all.
The reason I ask is that a couple of years ago I was involved in a scheme where the 11kv/433V Dyn11 Tx (No onboard isolator) was installed and the ACB was some 40-50m distance away. The DNO made us install a local ACB within 15m (cable length) of the Transformer LV terminal box. I...
Hi,
Can anyone tell me if there is a minimum allowable cable distance from the LV output terminals of a MV/LV transformer, say 1MVA, 11kV/433V to the CB, and what regulations/standards will apply in the UK.
Thankyou.
Old Relay.circa 1970's
Can anyone tell the time a Reyrolle 3B3 relay takes to trip.
The relay is set up as a REF. Instantaneous.
Set for 15V (0.5A) sec current from CT (1200/5)
30ohm resis in parallel with relay.
ie what is defined as "instantaneous" in this case, or is there a curve somewhere...
Hi,
An earlier thread (238-118313) shows a Generator withstand curve according to NEMA MG1-16.45
Is there an equivalent curve under IEC / BS / European standards, and if so could someone direct me to it or post it on this site.
Is there a minimum recommended time that standby low voltage (400V -...
Hi,

Thanks for your response.
I have being back to site to check on a few things.
The type of panel view is 2711 - T5A5L-1, Ser B, Rev E, FRN 4.46 and powered by 24V dc.
The dc connections are correct.
The cable between the PV550 and the SLC 5/03 is a 2711 - NC13, which as far as I am...
Hi,

Hi,
I am having some difficulty with the following, any input is gratefully received.
System
AB SLC 5/03.
1746 - HSCE Card for encoder 1024ppr encoder input.
1746 - N104V 2channel analogue input/output card.
Drive roller dia = 100mm (~4inch)
The encoder is mounted on the motor shaft.
The motor -...
Hi,

1746 - N104V 2channel analogue input/output card.
Drive roller dia = 100mm (~4inch)
The machine drive roller pulls material through the machine at about 10m/min
I need to measure the speed of the machine via the encoder...
Thanks jde777,
I have looked at the info and it is pretty thorough.
However I am still unsure whether or not I need a seperate power supply for the encoder, or does it derive its' power from the 1746HSCE card.

Hi,
I have been asked to modify a machine as follows.
On site there is a SLC 5/02 plc (1996), with spare slots.
I am using RS logix 500 V5.20 software. I know its a bit old but it works.
I have been asked to add the 1746HSCE card and connect an AB 845 diff encoder.
This is to measure the...
Hi,
Installation approx 50years old.
Low voltage 230/400V.(UK).
0.5sq in (~300mm2)4core PILC cable.
Cables/Gland Boxes located inside switchroom.
Problem
The black pitch/compound that is used to 'pot' the end of the cable into the cable gland/termination box is leaching / leaking out, and...
Higuys,
I have an existing AB 5/02 plc on an existing machine.
I have been asked to modify the machine so that it can determine the position of a product coming down the line.
Currently this is done by a proxy detecting a stud on a gear wheel.
It needs to be more accurate.
I propose to insert a...
