Fitting a bft kit with rigel 5, photocells, keypad, loop detector help

[easygates]

Question:

I hope you can help me. My brother (who is a qualified electrician) has asked me to help him install gate automation for a friend. We are both having a bit of difficulty understanding the wiring diagrams.

We have a pair of Lux hydraulic rams, a Rigel 5 control panel, a VX800 (2 2L) keypad, a pair of photocells (not sure what make), a loop relay (I believe a Procon) and an exit button.

We understand the connections for the rams & capacitors.

I believe that the VX800 should be connected:
Power is connected from 20 & 21 on Rigel to 1 & 2 on VX, connect terminal 3 (C1) on VX to 27 on Rigel, connect terminal 4 (NO1) on VX to 29 on Rigel

I believe the exit button should be connected across terminals 2 & 10 on the VX.

For the photocells I believe the TX power should be connected to 20 & 44 on the Rigel and the RX power to 20 & 21. I can’t remember the make of the cells but I do remember that the RX only had 4 connections, which is confusing as the diagrams in the Rigel manual all show 5. Would these go to 35 & 36 on the Rigel or do you need more information?

The loop defeats me completely, but I guess you would need more information before you can advise me.

Thank you in advance for any help you can give me.
