Preface
Purpose
This document is an overview of installation procedures, usage and hardware specifications for W.E.S

1 Product Overview
1.1 W.E.S Series
The Helios W.E.S. is a supplemental emergency stop system allowing workers to stop machinery and
equipment using a personally carried transmitter. The WES system enables a worker or supervisor to
open a relay that can be used to immediately disconnect the power to equipment from where the
individual is located or from the unit by activating the stop button.

The W.E.S. panel is comprised of the following components
1. Enabled Light
2. Alarm Light
3. Reset Button
4. Stop Button
2 V 1.2
Fig. 1.1 – W.E.S. 2000 Base panel
1.3 Standard Equipment/Components
Your system will come with the following equipment included:
1. W.E.S base station
2. Signaling transmitter
1.3.1 W.E.S Base
The W.E.S. base is a polycarbonate enclosure housing status lights, stop button, reset button
antenna and mounting points.
Internally there is a user replaceable 250V 15A Fuse
1.3.2 Signaling transmitter
The signaling transmitter may be one of a handful of transmitters designed for functionality in
different environments. See documentation specific to the handheld device assigned to your
base unit.
Note: The handset and and a W.E.S. unit are normally configured to work together. Some
units are programmed to restrict which handsets will trigger the alarm state. Always test and
ensure you are using the correct handset for your system. If in doubt test it to ensure it will
work.
2 Installation
See Helios W.E.S. E5 Install Guide
3 Operation
3.1 Base Unit:
When power is supplied to the base unit the red “Alarm” LED will be on, And the relay contacts will be
open (In the alarm state the output relay contacts will be open). The base unit will always start in the
“Alarm” state when powering up.
To Enable: Press and hold the “Reset Button” until the green “Enable” led comes on and the red
“Alarm” LED goes out. (In the enable state the output relay contacts are closed)
If the panel will not turn on the “Enabled” light when pressing the reset button, check to ensure the
push stop button is not depressed or that there are no handsets with an active alarm.
While the system is displaying the green “Enabled” LED the relay contacts are closed and the equipment
wired to the base should be functional depending on your installation and procedures.
Activating the E-Stop Alarm
An E-Stop can be initiated in two ways, locally via the E-stop switch located on the front of the unit and
remotely via the wireless remote.
Pressing the Large Red E-stop button on the face of the unit will open the relay contact, the
“Alarm” LED will come on and the “Enable” LED will turn off.
3 V 1.2
Pressing the stop button on the handset will open the relay contact, the “Alarm” led will come
Problem
Check/Solution
Relay contacts will not close
Check on board fuse, replace as necessary
Reset button does not enable unit
Ensure stop button is not engaged
Check that all transmitters are not in alarm mode
Handset does not trigger alarm when activated
Ensure handset is on and is the correct unit for
your W.E.S System

on and the “Enable” led will turn off.
Reset the system
If the system has been set into alarm mode by either the button or the transmitter the red “Alarm” light
will be on and the system will look the same as when it was first powered on.
1. If the system alarm was initiated via the E-stop switch, twisting the Estop button clockwise will
disengage the E-Stop.
2. If the system alarm was initiated via handheld, reset or disable the handheld that is transmitting
the alarm and then wait 10 seconds before resetting. For safety reasons when the system is set
into alarm mode via a transmitter the system has a time out period before you may enable the
equipment again.
3. After waiting 10 seconds press the reset switch until the enable light comes on and the alarm
light goes out. (The relay contacts will close). If the enable light shows green but turns off
immediately after releasing the equipment is still in alarm mode.
a. If the wireless transmitter was used wait another 10 seconds before attempting to reset
the system
b. If there is a handset still currently in alarm, or the E-Stop button is still depressed the
W.E.S. will not enable as long as there is a valid alarm state.
3.2 Testing
It is recommended the W.E.S. System be tested before every use to ensure you are using the correct
handset and the system is functioning properly.
To conduct a full test, enable the W.E.S. System and ensure the green “Enable” light turns on and then
trigger a stop using the wireless handset. Ensure the W.E.S. triggers into alarm mode right away and
your equipment is disconnected. If the handheld does not trigger the alarm commence troubleshooting
as follows.
