NNTTRROODDUUCCTTIIOON

1.1 PRODUCT OVERVIEW

The SPLT is a free standing accessory designed to protect the PPC from liquid contamination returning from the system or device under test.

The SPLT is made up of a stainless steel body with an internal X-Type coalescing filter and a bottom drain port fitting with an electrically actuated purge valve. The filter and valve assembly is installed in a mounting stand.

NNSSTTAALLLLAATTIIOON

2.1 PNEUMATIC

Figure 2. PPC with SPLT and DUT

Be sure SPLT is at low point of pneumatic system.

The SPLT is intended to collect and exhaust liquid contaminants that may be present in the device or system under test so that they do NOT return to the PPC.

The SPLT is installed in the test connection line at a low point between PPC and the device or system under test. The SPLT pressure connections are 1/4 in. NPT female.

Teflon™ tape or another sealing material should be used to assure leak free connection of adaptors

installed in the SPLT pressure connections.

Proper SPLT operation is dependent on the gas flowing through it in the correct direction. Make sure to connect the SPLT to the device or system under test and the PPC following the connector port labels on the SPLT.

Connect the SPLT electrically to the PPC rear panel DRIVER connection and to the SPLT term inal block (see Section 2.2).

The SPLT must be mounted vertically with the purge valve at the bottom to perform properly. The SPLT MUST be at a lower point in the system than the PPC and/or the device under test. In operation, liquid contaminants collected from the device or system under test will be exhausted through the SPLT purge valve.

SPLT™ USER’S MANUAL

Liquid contaminants will be forcibly ejected from the SPLT purge tube. Provision for collecting the purged

liquids should be considered when installing the SPLT.

Excessively dirty or wet filter elements can adversely affect pressure control.

2.2 ELECTRICAL

In order to take advantage of the automatic purging feature of the PPC, the SPLT valve MUST be connected to the PPC external driver #8.

Connect like this if drivers connector with attached cable was included with SPLT:

Connect drivers connector to DR IVERS connector on back panel of PPC. Attach the two wires to the

terminal block on the SPLT

Connect like this if you have SPLT without drivers connector:

Solder (2) 24 gauge wires of desired length to the 12-pin connector provided with the PPC. Connect

(1) wire to pin L and the other to pin B. Connect drivers connector to DRIVERS connector on back panel of PPC. Attach the other end of these wires to the terminal block on the SPLT.

Polarity is NOT significant to the operation of the purge valve.

AAIINNTTEENNAANNCCE

4.1 GENERAL

The maintenance of the SPLT consists of cleaning or replacing the internal coalescing filter. A dirty filter should be rinsed with a degreasing agent to remove oil and particulate matter. A filter with physical damag e should be replaced.

4.2 REMOVING AND INSTALLING THE SPLT FILTER

See Section 4.5 for part number and figures referred to in the filter replacement procedure.

Remove power and pressure connections prior to disassembly.

The procedure for replacing the coalescing filter in the SPLT is as follows:

Disconnect pressure tubing to the SPLT if necessary.

Disconnect power leads to the exhaust valve solenoid (3137053). Disconnect drain tube (3232357) from elbow adaptor (3133040). Unscrew lower housing of filter using flats on the lower housing.

Lower the housing with attached valve and fittings through the slot in the mounting bracket.

Remove filter, clean cavity (3136996). Install new filter. Re-assemble SPLT.

Leak Check.
