Power Shield PSATS3K Automatic Transfer Switch User Guide

Introduction

The PowerShield® ATS is designed to accept two independent power inlets (primary and secondary) to supply power to the load from either power source. Should primary power source fail, the secondary will automatically back up the connected equipment without any interruption. The transfer time from one line to another is seamless to the connected equipment. After switching to a secondary power source, the ATS can also switch power back to the primary input when power to the primary input is restored.

Important Safety Warnings

Before using the unit please read all instructions and cautionary markings on the unit, this manual and the batteries.

WARNING!! The ATS must be connected to earth when in use.
In line with current regulations, only use the cables that have been supplied with the machine. The power supply socket must be easily accessible to the operator.

WARNING!! The ATS has been designed exclusively to operate indoors. It is essential to install it in areas where no inflammable liquids or gases, or other harmful or noxious substances, have been stored.

ATTENTION!! A soft damp cloth may be used to clean the outside of the machine (always with the system disconnected from the mains power supply and load).
Do not use any type of solvent as this may damage the external finish of the machine.

ATTENTION!! The ATS has been designed exclusively for professional use.

NOTE: These instructions may be modified by the wiring regulations in force in the country where the ATS is purchased.

Mounting the Unit

NOTE: If the ambient temperature exceeds 40 °C, ventilation is required

Connecting the Unit

Connect the ATS input plugs “input source A connector” and “input source B connector” to the two independent power sources or UPSs using either the SCHUCKO-IEC or IEC-IEC 16A cables supplied.

Plug the load into the output 10A (“Output 1 and 2”) or 16A (“Output 3”) sockets depending on requirements.

Operation

Power On/Off
Turn the input power switch to the “ON” position. The output will then be supplied by the source set as selected.

Setting the Preferred Power Source
It is possible to set the power source preference by pressing “source preference selector”. The default power source is “Source A”.

Communication Port

The ATS is supplied with the following communication ports:

Serial port is available with RS232 com. port and USB com. port on the front panel.
NOTE: the use of one port automatically excludes the other.
Contact port on the rear panel.

Serial Ports: RS-232 & USB connectors

NOTE: The utilization of the communication port is optional and it is not necessary for the normal function of the ATS.

Contact Outputs

The contact outputs consist of six (6) pins numbered from left to right (see fig. 1), which can be connected to an external monitoring system (such as a BMS) in order to monitor the operational status of the ATS.

The external equipment must be within the rating of the contacts
Fig. 1: Contacts Connector

The Contact Connector provides the following connections:

Pin 1: Common contact.
Pin 2: “Source B” active contact – pins 1 and 2 closed = output supplied by “Source B”
Pin 3: “Source A” active contact – pins 1 and 3 closed = output supplied by “Source A”
Pin 4: “Source A” status OK contact – pins 1 and 4 closed = “Source A” is present and normal
Pin 5: “Source B” status OK contact – pins 1 and 5 closed = “Source B” is present and normal
Pin 6: Status OK contact – pins 1 and 6 closed = ATS operation normal

The following diagram shows the contact configuration

**Fig. 2: Contact Connections

ATTENTION: Contact Connector pins are rated at a current of 8A and voltage of 250Vac.

Trouble Shooting

Problem	Possible Cause	Solution

The ATS with the mains voltage present, does not turn on.

(The LEDs does not flash and no alarm sounds.)

| Input plugs not connected| Connect the mains to the input plugs as indicated in the installation section.
Input switch in “OFF” position| Turn the input switches “ON”

Input power failure

| Check that the mains voltage is present or check if the UPS supplying the ATS is on.
Upstream Fuse or CB disconnected| Reset the CB or Fuse Warning: check that there is no overload or short- circuit at the output of the UPS.
The load is not powered.| Output sockets not connected| Connect the load to the output sockets
10A Internal thermal protection device has tripped| The Internal protection will operate in the event of a short circuit or overload on one of the 10A output sockets. The thermal protection can be reset by pushing the button which will result in the power being reconnected to the load. Therefore prior to attempting a reset of the thermal protection, check the rating of the connected loads and determine if there is any overload. Then once reset, reconnect each load one at a time to ensure no problems exists.
No display or display provides incorrect information.| There is a power supply problem in the display.| Shut down the ATS completely and wait for a few seconds.

Switch the ATS on again, if the problem persists, contact the nearest technical support centre.

The display is off but the load is powered.| There is a power supply problem in the display.| Contact the nearest technical support centre.

If there is any abnormal situation not listed above, please call PowerShield Service immediately for professional Technical Support
