1 Overview

There are 2 types of power supplies used in HP Indigo Digital Presses, Mean-Well and Lambda.All procedures described below are for Mean-Well and Lambda, unless specified.

This document describes how to check and adjust the voltage for the Lambda and Mean-Well,24 V and 48 V power supplies located in the PDU.

HP Indigo presses have two 48 V power supplies connected in parallel. The output voltages ofthese power supplies must always be 48 0.1 V.

If the two 48 V power supplies have out voltages outside the acceptable range, then the powersupply outputting the higher voltage takes over the work of both power supplies, and the secondpower supply shuts down. However, one power supplies does not supply enough power to thepress, leading to errors, failures and print quality issues.

HP Indigo presses also have a 24 V power supply, that must always have an output voltage of 24 0.5 V.

DANGER! This procedure includes steps that require the electrical power to remain on, whilevoltages are measured.

It is especially dangerous in the following presses where the relevant power supplies are located inconfined areas of the PDU: HP Indigo press w3200, HP Indigo press w3250, HP Indigo press ws4000,HP Indigo press ws4050, HP Indigo press ws4500, HP Indigo WS4600 Digital Press,HP Indigo press 3050, HP Indigo press 3000.

When you need to replace a 48 V power supply, it is recommended to order 2 x 48 V powersupplies, to ensure that the HP Indigo Digital Press will have 2 identical power supplies. If you findthat the new power supplies are identical to the existing power supply, then you can send one ofthe new power supplies back to the stores, un-opened.

When replacing power supplies, it is recommended to check the voltages of all the power supplies(and adjust or replace if necessary).

CAUTION: 1. If the output voltages are not within the range of 48 0.1 V, one of the powersupplies will be overloaded, and may trip.

CAUTION: 2. When replacing power supplies, make sure that both are from the same supplier either both from Lambda, or both from Mean-Well. Never mix the two.

CAUTION: 3. For Mean-Well power supplies, make sure that both power supplies either

have, or don't have the following label: .

This label indicates that this is a customized power supply. Never mix the two.

For presses with 7 colors, it is recommended to check the voltages of all the power supplies (andadjust or replace if necessary).

CAUTION: Power supplies with the label: , indicates that

it is a customized power supply, and is only suitable for presses with 6 colors or less. Presseswith 7 colors need power supplied that do not have this label.

2 48 V power supply procedures

Checking the 48 V power supplies and adjusting1. Shut down the press software. Turn off the press.

2. Slide the utility cabinet open. Open the PDU door.

3. Disconnect the JD3 connector.

CAUTION: Wait until the green LED on the power supply turns off before connecting /disconnecting wires, to avoid damaging the power supply.
