Introduction

This guide is showing how to change the customer-facing safety radar to triggering the gate to open by approaching it. (The radars will always be triggering the gate when detecting movement).

Tools needed

A wide flat chisel (To unlock the hatch on the SigmaGate gate.)
A tiny flat chisel (For re-connecting cables inside the SigmaGate and for tuning the radar sensitivity.)

Guide

NOTE: Both sides of the SigmaGate has one radar each as standard. This guide will start with how to change one side and when done with the first side, it is just to repeat the steps again for the other side.

Before starting to do any work, make sure you open SigmaGates using the remote and/or turn the gate off by turning the power key switch to the vertical potion or cut the power to the gate.
NOTE: The power key switch will only cut the power to the motor and not the whole gate. This needs to be done on each side.
Start by locating the hatch of the left-hand side gate while exiting through the gate.

NOTE: The radars is always installed behind the hatch that is facing the customer when exiting through the gate.
There is a small lock switch located in the top corner of the hatch that needs to be turned around to unlock it.
if the crack is horizontal, the hatch is locked:

If the crack is vertical, the hatch is unlocked:
To unlock the hatch you need a wide flat chisel or similar to unlock the hatch. Turn the lock clockwise until the crack is vertical.
To remove the hatch, lift it from underneath and pull it out at the same time. When the hatch is opened up, please disconnect the earth cable connecting the hatch to the gate body.
Just pull the earth cable straight out using your hand and then put the hatch aside.

See video of how to remove the hatch and get into the gate (steps 2-7):
Now, locate the radar behind the hatch.
On the left side, the radar is located in the top right corner behind the hatch.
On the right side, the radar is located in the top left corner behind the hatch.
When you found the radar, locate the grey connecting cable going from the back of the radar in to the gates Main PCB.
The grey cable coming from the radar should be connected like this when functioning as a safety radar:

+12v = Green wire

GND = Brown and Yellow wires

OPEN NEXT/ SCO CLOSE = White wire
To now change the function from working as a safety radar to function as an approach radar we need to move the white wire from OPEN NEXT/SCO CLOSE to FRONT OPEN. The Green, brown and yellow wires will stay as is.

+12v = Green wire

GND = Brown and Yellow wires

FRONT OPEN = White wire
To disconnect a wire you will have to pull out the green PCB connector from the main PCB and use the small flat chisel to loosen the cable from the connector and put it in where it should be.

See video of how to connect the radar as an approach radar:
When the radar is connected as an approach radar, make sure the radar detects movements. You can see that by approaching the radar with you hand and a red LED light will illuminate on the radar itself. That means the radar detected the movement:
Now you will have to to the same thing to the other radar inside the right-hand side gate.
Repeat the steps from 2 - 13 before continuing.
NOTE: The main PCB board might be on the other side of the gate than where the radar is located. If that is the case, just open up the hatch on the other side of the gate to locate the main PCB.
When both radars are connected as approach radars it is time to tune the sensitivity of the radars to open in time when a person approaches it.
Before tuning the radars, make sure you power on the gate again and/or turn on the power key switch to make sure the gates is operational again.
Adjust the potentiometer on the side of the radar as shown in the image below to set the detection range.

Maximum sensitivity: Potentiometer turned all the way clockwise.

Minimum sensitivity: Potentiometer turned all way anti-clockwise.

NOTE: The tuning of the radar will be the same no matter if it got the dial on the right or left side of the radar.

NOTE: The trigger sensitivity of the radars will reduce once the hatch is put back so make sure to test the trigger distance with both hatches on to make sure they still trigger the gate top open in time for someone exiting.
