OPERATING FEATURES

1 OPERATING FEATURES

1.1 DESCRIPTION

The PWR-480W is an electrical cabinet housing a 24 Vdc power supply which is used to

power up a varying number of reading devices (depending on the product), along with their

relative accessory devices. See chapter 4 for details.

As shown in the Electrical Diagram in Appendix A, the AC Input Line passes through a

protective thermo-magnetic circuit breaker and connects to the monophase switching power

supply.

The 24 Vdc output power is connected to the output terminal blocks divided into two

sections: a direct connection block and a current-limiting block (composed of three sections).

While the direct connection block is protected by the internal power supply features, the

current limiting block is protected by three Miniature circuit breakers (MCB), 4 A, 1p, C-Char.

Two output power supply status monitoring signals (DC-OK) are provided to connect to an

optional digital alarm. If for some reason the output voltage is reduced by less than 90% of

nominal, these lines open.

1.2 OUTPUT PROTECTION

The power supply implements both output short-circuit and overload protection.

1.2.1 Short-Circuit Protection

If a short-circuit occurs on the output lines causing the output voltage to drop below 20 Vdc,

the power supply enters hiccup mode where power is supplied for 2 seconds and then shuts

off for 17 seconds. This procedure is repeated until the short-circuit is resolved. Refer to the

diagram below.

Figure 3 – Short-Circuit Protection Hiccup Mode

PWR-480W INSTALLATION MANUAL

1.2.2 Overload Protection

In the event of sustained output current overloading, overload protection is provided where

overload power is supplied as explained in the examples below:

Example 1: Up to 120% power overload

The overload is supplied for approximately 12 seconds and then is reduced (Voltage and

Current) to about 104% power continuously. In this case output voltage is reduced but

remains above 20 Vdc.

Figure 4 – Overload Protection up to 120%

OPERATING FEATURES

Example 2: 125% power overload

The overload is supplied for approximately 10 seconds and then is reduced (Voltage and

Current) to about 95% power for another 10 seconds. In this case the output voltage falls

below 20 Vdc and therefore the power supply shuts down for a recovery time of 17 seconds.

This procedure is repeated until the excessive current overload is resolved.

Figure 5 – Overload Protection at 125%

Example 3: 150% power overload

The overload is supplied for approximately 4 seconds and then is reduced (Voltage and

Current) to about 48% power for another 2 seconds. In this case the output voltage falls

below 20 Vdc and therefore the power supply shuts down for a recovery time of 17 seconds.

This procedure is repeated until the excessive current overload is resolved.

PWR-480W INSTALLATION MANUAL

2 PRE-INSTALLATION CHECKLIST

This chapter can be used as a checklist to verify all the steps necessary to complete

installation of the PWR power supply.

CAUTION: Opening the cabinet requires a key that should be used by a

person adequately advised or supervised by an electrically skilled person to

enable him or her to perceive risks and avoid hazards which electricity can

create. Internal components guarantee an IP20 degree of protection against

direct contact.

1) Read all information in this manual before installation, paying particular attention to all

Caution and Warning notes.

2) Mount the PWR to the Station frame using the brackets and bolts provided in the

package. See par. 3.1.

SYSTEM WIRING: DC OUTPUT

3) Plan all the cable entry points to avoid unnecessary holes and pass the cables through

the Cable Entry Plate as described in par. 4.

4) Connect your devices to the PWR according to the information in par. 4.2.

SYSTEM WIRING: AC INPUT

5) To comply with EN 60950-1:2007 par.1.7.2.2, par. 2.7.1, par 2.7.4, par. 3.4.6, and to

protect the AC input connection to the device; a disconnecting device with built in

overcurrent and earth protection shall be installed external to the equipment according

to local regulations.

According to EN 60950-1:2007 par. 3.2.3; the AC input cable must have a maximum

diameter of 14mm and the conduit a max diameter of 16mm.

6) With AC line voltage OFF, wire the AC Line to the AC Line Input Terminal Block (see

par. 5).

SYSTEM WIRING: TEST

7) Apply the AC line voltage from the building installation or the DWS-SWITCH and check

that the PWR powers up correctly. The green DC-OK light should be on steady and the

overload light (red) should be off.

8) Close and lock the PWR enclosure and check that it does not open (lock functions

correctly).

The PWR-480W installation is now complete.
