1. INTRODUCTION

1.1 PRODUCT OVERVIEW

RPM3/HPMS A30000/A6000-AF is the combination of an RPM3 A5000/A6000-AF reference pressure monitor and an HPMS High Pressure Mounting System. The combination of an RPM3/HPMS A30000/A6000-AF and an OPG1-AF oil pressure generator make up the HGC-30000-AF hydraulic gauge calibrator. The OPG1-AF has it s own Operation and Maintenance manual.

RPM3 A30000/A6000-AF is a stand-alone, microprocessor driven, reference pressure monitor intended to accurat ely measure oil pressure in a variety of pressure calibr ation, measurement and testing applications . It has been designed t o provide very high perfor mance and extensiv e features combined with maximum v er s atility and ease of use. RPM3 A30000/A6000-AF is a special version of the standard DHI RPM3 product configured specifically for the USAF HGC-30000-AF hydraulic gauge calibrator.

The HPMS mounts the RPM3 at a conv enient viewing angle and c ontains t he hardware t o isolat e the RPM3’s low pressure tr ans ducer (A6000) when the high press ure transducer (A30000) is in use.

RPM3 A30000/A6000-AF uses tw o high accurac y ref erence pres sure t ransduc ers (RP Ts) and an onboard barometer t o m eas ur e pr es s ur e.

RPM3 A30000/A6000-AF is controlled locally by the operator using its front panel display, keypad and foot pedal or remot ely by a computer using ASCI I character command strings over its RS-232 and IEEE-488 interfaces.

RPM3 A30000/A6000-AF has s ix pressure m easurement r anges from 0 t o 2 000 psi (7 MPa) t o 0 to 30 000 psi (200 MPa) in gauge and absolut e m eas ur em ent modes.

1.2.2 PRESSURE MEASUREMENT SPECI FICATIONS

RPM3 A30000/A6000-AF is configured with two reference pressure transducers (RPT). Each transducer has three ranges. The RPTs are of the absolute pressure type with an evacuated, permanently sealed reference. Absolute RPTs measure both absolute and gauge pressure. Gauge pressures are defined by offsetting atmospheric pressure dynamically with compensation for atmos pher ic c hanges us ing an on board barometer.

2.3.5 FOOT SWITCH CONNECTION

Connect the foot switch supplied in the RPM3/HPMS ac cessories to the HPMS rear panel electrical connection labeled FOOT SWITCH. Place the foot switch on the floor at a convenient location. The FOOT SWITCH function is equivalent to the RPM3 front panel [ENTER] key and may be used fr equently while running tests and c alibr ations.

2.3.6 TEST PORT CONNECTION

A single high pressure TEST port is prov ided on the rear panel of the HPM S . The test port connection is a DH500 F. DH500 is a gland and collar ty pe fitting f or 1/4 in.

(6 mm) coned and left hand threaded tube. DH500 is equivalent to AE F250C, HIP HF4, etc.

Connecti on to OP G1 if the RPM3/HPMS is Part of an HGC-30000-AF S yst em

If the RPM3/HPMS was delivered as part of an HG C-30000-AF Hydraulic G auge Calibrator, an OPG1 Oil Pressure Generator/Controller was delivered with it. The OPG1 includes a fittings kit with the necessary fittings to interconnect the RPM3/HPMS and OPG1 and instructions on making the connection. S ee the OPG1-30000-A F manual.

USE THE CORRECT PRESSURE CONNECTORS: The RPM3/HPMS TEST port fitting is a DH500 F (see Section 1.2.1). It is NOT a 1/8 in. NPT F . Never use fittings other than the correspo nding male fittings in these connec tors. D amage to the connecto rs and d angerous failure under pressure co uld res ult from using incorrect fittings.

DO NOT AP PLY PRESSURE UN TIL YOU ARE FAM ILIAR WITH OPERATION : The RPM3/HPMS rear panel test port connects internally to both the RPM3’s 6 000 psi (40 MPa) and 30 000 psi (200 M Pa)RPTs. T he valve on the front o f the HPMS isolate s the low press ure RPT when the high pressure RPT is in use. Do not app ly pressure to the RPM3/HPMS until you are familiar with its operation and know how to protect the low pressure RPT from overpressure (see Section 3.1.8). FAILURE TO PROTECT THE LOW PRESSURE RPT FROM OVERPRESSURE MAY DESTROY IT. DAMAGE D UE T O RP T OV ERPRESSURE IS NO T COVERE D BY THE PRODUCT WARRANTY.

2.3.6.1 THE RPM3 AT M PORT

The ATM pass through on the RPM3 rear panel is connected to the RPM3’s onboard barometer. This connection assures that the on-board barometer measures ambient atmospher ic pressure rather than the press ure inside the RPM3 case that may vary slightly from ambient pressure. The ATM port should be left open and unobstructed.

NEVE R plug or obs truct the ATM pas s through as this ma y adverse ly affect gauge mode operation and autozeroing on an absolute transducer.

2.3.7 SETTING UP FILE SEQUENCES

RPM3 supports automated test/calibration sequences. Sequence parameters for testing specific DUTs can be stored in Sequence Files and recalled when a Sequence is run. Consider setting up Sequence Files for frequently t ested DUTs as part of t he RPM3 set up process (see Section 3.3.6).

2.4 POWER UP AND VERIFICATION

2.4.1 APPLY POWER

Connect the RPM3 power cable to an electric supply of 85 to 264 VAC (47 to 440 Hz). Observe the front panel display as RPM3 initializes, error checks and goes to the main run screen (see Sect ion 3.1. 2). Check t hat one of the t wo green Valve St atus LEDs on t he front panel of the HPMS is lit (the red LED should NO T be ON).

RPM3 is always powered and active when power is supplied through the rear panel power connector. The front panel ON/OFF key controls a soft ON/OFF function (see Section 3.1. 4).

If the RPM3 fails to reac h the main run sc reen, servic e is required. Recor d the sequence of operation and displays observed and contact a DHI Authorized Service Center (see Section 7.2, Table 18).

If neither of the green LEDs on the HPMS front panel lights, check that the 9-pin D-Sub accessory cable at the rear of the RPM3 itself is properly connected to the ACC. J1 connector.

The active range o n power up is the sam e as the range that was active at the last power down (see Section 3.1.6).

2.4.2 CHECK PROPER PRESSURE MEASUREMENT OPERATION

2.4.2.1 CHECKING ABSO L UT E MODE PRESSURE MEASUREMENT

Check that the RP M 3 RP Ts operate properly in abs olute mode. Open the RPM3/HP MS TES T port t o atmosphere. Put the valv e knob in the HPMS

front panel into the Lo RPT Active position. This opens the Lo RPT t o the HPMS TEST port.

Press [MODE] on the RPM3 and select absolute. Change the pressure unit of measure using [UNIT] if desired (see Sec tion 3.2.3).

Observe the RPM3 indicated pressure. Check that t he value is equal to at mospheric pressure [RANGE] and [ENTER] to change ranges. Check that the values of atmospheric pressure measured by the different ranges agree with each other within RPM3 measurement tolerances (see Section 1.2.2.1). If they do NOT agree within

± 5 psi. Repeat this process for all the ranges on both RPTs using

RPM3/HPMS A30000/ A6000- AF Operation and Mai ntenance Man ual

tolerances, RPM3 may need calibration or repair.

2.4.2.2 CHECKING GAUGE MODE PRESSURE MEASUREM ENT

Open the RPM3/HP MS TES T port t o atmosphere. Put the valv e knob in the HPMS front panel into t he Lo RPT Active position. This opens the Lo RPT t o the TEST port.

Press [MODE] on the RPM3 and select gauge. Change the pressure unit of measure using [UNIT] if desired (see Sec tion 3.2.3).

The value indicated should be near z ero ( then press [AutoZ]. This runs AutoZ to zero the range (see S ection 3.2.10). Upon return to the m ain run screen, observe that the indication of m easured pr essure has zeroed.

Use [RANGE] and [ENTER] to change ranges (see Section 3.2.2) and repeat the zeroing process for each range (the two minute wait does not need to be repeated each time).

If a range fails to zero properly, RP M 3 m ay need r epair .

It is normal for RP M3 to indicate a value o ther than zero when vented when gauge mode is first entered or ra nges are changed, especially if Auto Z is OFF, RPM3 ha s been OFF for so me time, its location ha s changed or the fluid head to which it is connected has changed.

3.1 GENERAL/MANUAL OPERATION

RPM3/HPMS is designed to offer the optimum balance bet ween simple, str aight forward operation and the availability of a wide v ar iety of funct ions with a high level of operator disc r etion if desired.

The RPM3 provides the local operator interface is through a front panel 2 x 20 character alphanumeric display, a 4 x 4 multi-function k ey pad and an [ENTER] foot switch.

The HPMS mounts the RPM3 at a convenient viewing angle and includes a valve and visual indicators to isolat e and protect the RP M3’s 6 000 psi RPT (Ranges L1, L2, L3) when using t he 30 000 psi RPT (Ranges H1, H2, H3) (see Section 3.1.6).

3.1.1 KEYPAD LAYOUT AND PROTOCOL

The RPM3 has a 4 x 4 keypad and an [ENTER] foot switc h for loc al operator access to dir ect functions, function menus and for data entry.

1. The Editing and Execution keys are for

execution, suspending execution, backing up in menus and editing entries.

The Menu/Data keys provide access to

2. function menus from the main run screen. The menu name is on the bottom half of the key. The SETUP menu is for more frequently used functions (see Section 3.3).

The SPECIAL menu is for functions that are NOT generally used as a part of day to day operation (see Section 3.4). These keys enter numerical values when editing.

The Function/Data keys allow very

3. commonly used functions to be accessed directly from the main run screen by a single keystroke. The name of the function is on the bottom half of the key (see Section 3.2.1). These keys enter numerical values when editing.

[ENTER] Foot Switch (not shown) acts in exactly the same manner as t he keypad [ENTER]

3.1.6 MULTIPLE PRESSURE RANGES

RPM3 A30000/A6000-AF has t wo ref erence pres sure t ransducer s (RP Ts) eac h of which has three ranges for a total of six pressure ranges. This multi-ranging feature allows measurement uncertaint y to be optimized for the range of pressur e in which you ar e working. Generally, the bes t range to select ( see Section 3.2.2) is that whose full scale is closest t o, but greater than, the maximum pressure of the device or system under test.

RPM3 handles all of the dat a operat ions needed to mak e r ange c hanges occur t ranspar ently to the user when the RA NGE f unct ion is used f or range s election. For a range change t o be executed, the current pressur e applied to the RPT on which the r ange is being select ed must be lower than the current upper limit (UL) of that range (see Section 3.2.5). The RPM3 Sequence feature automatically selects the most appropriate range based on the range of the device under test (see Section 3. 2.11).

When the range is changed, the upper limit automatically changes to the default for that range or to the last upper limit set for that range. In addition, most other functions and settings are range specific (see Section 3.2.2).

RPM3 A30000/A6 000- AF ha s s ix ranges. In general, s ettings and operationa l adjustments are specific to the range currently in use, as if you had six instruments rather than one. The DISP LAY function, HEAD functions and AUTO RE ADRT function are NOT range specific. In remote mode, m ost settings are RPT specific rather than range specific (see Section 4.3 ).

3.1.6.1 RANGES AND IDENTIFICATION

The active RPT and range is cont inuously indic ated in t he upper right hand cor ner of the main run screen and m os t other screens.

Hi RPT: The A30000 RPT whose maximum range is 30 000 psi (200 MPa) is referred to as the Hi RPT.

Lo RPT: The A6000 RPT whose maximum r ange is 6 000 psi (40 MPa) is referred to as the Lo RPT.

Range 1, 2 or 3: The three ranges of each RPT are r eferred to as 1 = lo range, 2 = mid range, 3 = hi range. The Lo RPT ranges, low to high, are L1, L2, L3. The high PRT ranges, low to high, are H1, H2, H3.

3.1.7 AUTOMATED TEST/CALIBRATION SEQUENCES

The RPM3 SEQUE NCE function supports “quick” and “file” automated calibrati on sequences. These automatically set the appropriate RPM3 range, resolution and stability limit based on the characteristics of the device under test. They also prompt the user through the increments of the calibration sequence and log calibrat ion data. The SEQUENCE funct ion should be used for most common calibration tasks, especially calibration of analog pressure gauges (see Section 3. 2.11).

RPM3/HPMS A30000/ A6000- AF Operation and Mai ntenance Man ual

3.1.8 HPMS (HIGH PRESSURE MOUNTING SYSTEM)

The HPMS (high pressure mount ing system) holds the RPM3 at a convenient viewing angle and includes a valve and visual indicat ors to isolate and prot ect the RPM3’s 6 000 psi RPT (Ranges L1, L2, L3) when us ing the 30 000 psi RPT (Ranges H1, H2, H3).

m OPERATION

Numerical references in this Section ref er to Figure 1. In normal use, t he operator’s only interaction wit h the HPMS is t o operate the isolation

valve knob to connect and disconnect the Lo RPT from the TEST port. The valve’s operation is prompt ed by the Valve Posit ion LEDs ( 1, 3).

The Lo RPT isolation valve (2) isolates and protects t he Lo RPT from the TES T port when it is closed (knob f ully CCW) and opens the Lo RPT to the T EST port when it is open (knob fully CW).

The Valve Position LEDs (1, 3) indicate the position in which the valve knob s hould be set based on the current range selection on t he RP M 3. If a range on the Hi RPT (H1, H2 or H3) is selected, the LO RPT SHUT OFF LED (1) is lit indicating that t he valve knob should be turned fully CW to close t he valve, prot ecting the Lo RPT from high pressur e. If a range on the Lo RPT (L1, L2 or L3) is selected, t he LO RPT ACTIVE LE D (3) is lit indicating that the valve knob should be turned fully CCW to open t he valve, connect ing the Lo RPT to t he test pressure.

The HPMS isolatio n va lve (2) must always b e in the clo s ed position (knob fully CCW) when operating a t p re ss ure grea te r tha n 6 000 psi (40 MPa ).

The CAUTIO N LO RPT ACTIVE LED (4) is used to indicate t hat the Lo RPT is active and provide a warning when the Lo RPT is active but a Hi RPT range is selected on the RPM3.

The CAUTION LO RPT ACTIVE LED (4) is driven by the value of pressure currently measured by the Lo RPT, it is not driven by the valve posit ion as there is no sensing of the valve position.

The CAUTION LO RPT ACT IVE LED (4) has three possible conditions:

• LED is OFF: The Lo RPT is NOT act ive. The Lo RP T is considered ac tive when it

measures a pressur e gr eater than 30 psig (200 kPa) .

• LED ON continuously: The Lo RPT IS active and a Lo RPT range is selected on
