NOTENOTENOTENOTENOTE: This equipment has been tested and found to comply with the limits for a ClassA digital device, pursuant to part 15 of the FCC rules.

These limits are designed to provide reasonable protection against harmful interfer-ence when the equipment is operated in a commercial environment. This equipmentgenerates, uses, and can radiate radio frequency energy and, if not installed andused in accordance with the instruction manual, may cause harmful interference toradio communications. Operation of this equipment in a residential area is likely tocause harmful interference in which case the user will be required to correct theinterference at his own expense.

This Class A, digital apparatus meets all requirements of the Canadian Interference.Causing Equipment Regulations.

Cet appareil numerique de la classe A respecte toutes les exigences du Reglementsur le material broilleur du Canada.

This device corresponds to requirements stipulated in 90/384/EEC andfeatures radio interference suppression in compliance with valid ECRegulation 89/336/EEC. Note: The displayed value may be adverselyaffected under extreme electromagnetic influences, eg. when using a

radio unit in the immediate vicinity of the device. Once the interference hasbeen rectified, the product can once again be used for its intended purpose. Thedevice may have to be switched on again.

Cet appareil correspond aux exigences selon la norme 90/384/CEE et est dparasitconformment la directive de la CE 89/336/CEE en vigueur.

DescriptionDescriptionDescriptionDescriptionDescriptionThe Ohaus I5S Indicator Standard is a rugged, reliable electronic weight indicatorthat is made in the U.S.A. and is designed to be easy to operate. It can be easilyconnected to Ohaus or other brands of Scale Bases. The I5S Indicator has beenNTEP tested and found to comply with Class III and IIIL requirements of NIST HB44for 1:5000 performance in pounds, kilograms, ounces or grams. The I5S Indicatorcan be wall, bench or tower mounted. The I5S Indicator can drive up to four 350ohm load cells and provides capacity selections up to 10,000 lbs/kgs with amaximum resolution of 1:20,000. The indicator is constructed of extrudedaluminum with removable plastic end caps and is extremely durable. The I5Soperates from six Alkaline "C" batteries and can also be powered externally usingthe AC adapter supplied. A six and a half digit LCD display which is 0.6 inches/1.5 centimeters in height provides easy visibility when working at distances fromthe indicator. Two switches mounted on the front panel enable simple set up ofconfiguration and feature parameters. A menu lock-out switch can be set to lockout various functions of the indicator to prevent settings from being changed.Accessories include: an RS232 Interface Kit, a Wall Mount Accessory kit, and aTower Mounting Accessory Kit.

2. Enter the Setup submenu and go tothe LOCSW parameter. Set theSETUP and CAL LOCSW param-eters to ON. Refer to the MenuLock-out Switch Setting on page2-10 for detailed procedures.

3. Set the menu lockout switch on theprinted circuit board to the ON posi-tion.

4. If an audit trail or paper seal will beused, install the End Cap and tightenthe two 6-32 phillips pan headscrews.

5. If a lead and wire seal will be used,replace the 6-32 phillips pan headscrews with the 6-32 hex socketsecurity screws and washers en-closed in the plastic bag containingthe accessories.

1. Press to obtain a zero read-ing.

2. Place an empty container on thescale base and read its weight onthe display.

TroubleshootingTroubleshootingTroubleshootingTroubleshootingTroubleshooting

PROBABLE CAUSE(S)Adapter not plugged inor properly connected.

Batteries dead or notproperly connected.

Load on scale base ex-ceeds allowable zero %entered in ZERO pa-rameter of Setup menu(see Chapter 2).

Retain Zero Data is en-abled in Scale menu.

Scale base motion or dis-turbances exceed cen-ter of zero criteria.

Desired unit not set toON in Scale menu.

RS232 communicationparameters set up incor-rectly.

Cable connections.

Scale base discon-nected.

LOCSW set to ON andmenu protection switchset to ON position.

REMEDY

Check power cord con-nections.

Make sure adapter con-nector is plugged all theway into the indicator.

Check battery connector.

Check orientation of thebatteries.

Make sure end caps aresecure on indicator.

Replace batteries.

Remove load on scalebase to less than enteredzero %.

Change allowable zero% in ZERO parameterof Setup menu (seeChapter 2).Normal operation whenthis feature is enabled.

Remove disturbances orreduce motion.

Increase averaging levelin AL menu.

Enable desired unit (seeChapter 2).Verify communicationparameters.

Check cable connec-tions.

Check connections.

Set menu protectionswitch to OFF position.

SYMPTOM

Unit will not turn on.

Cannot rezero indicator,or will not re-zero whenturned on.

Center of Zero displayindicator erratic or doesnot appear with no loadon scale base.

Cannot display weight indesired weighing unit.

DISPLAYEDMESSAGE DESCRIPTION

Flashes at 10 second intervals when batteries are weak. Approxi-mately 2 minutes of operating time remain.

Underload condition.

Overload condition.

Err 0: Invalid memory checksum, on either cal data, parameters, or both.Checksum is verified every time I5S is turned on. Check setupparameters in menus and recalibrate. If error persists, a hardwareproblem may exist and unit must be serviced.

Err 1: Overload error. (Interface only). This error shows as all uppersegments on the display.

Err 2: Underload error. (Interface only). This error shows as all lowersegments on the display.

Err 4: Invalid calibration error. This error usually occurs during thecalibration procedure when there is insufficient signal for the ScaleBase as compared to the indicator set up parameters.

In LFT operation, this error will occur if an attempt to calibrate theindicator when the active range of the load cell is less than1.2 mv/v for the active full-scale load. Recheck the load cell rating,set up parameters, and calibration weights.

Err 14: Attempt to zero balance when zero criteria are not met. Zerocriteria can change depending on user settings and whether or notthe indicator is doing a power-on zero or a normal zero. See power-on zero operation for more details.

Err 21: Calibration data does not match current Full Scale, Grad and CalPoint settings. Settings must be restored or the indicator must berecalibrated using the current settings.

Err 22: The current combination of Grad and Full Scale settings exceedsrated resolution (1:5,000 LFT, 1:20,000 non-LFT). This can occurif the user modifies the Full Scale setting, then attempts to exit theSETUP menu without entering the Grad submenu. Once the user

40

44444 Troubleshooting

entered the Grad submenu, graduation selection will be limited to choices that donot exceed rated resolution.

Err 23: Retain is enabled in the Scale menu, but valid Retain data does notexist. Normal power-on zero operation will occur. The new power-on zero, since Retain is enabled, will be written to the EEPROM andused as valid retain data the next time the indicator is turned on.

Err 24: An attempt was made to process an interface command that iscurrently locked by the lock switch.

Err 25: Attempt to leave the SEL submenu with all units turned off.

Care and MaintenanceCare and MaintenanceCare and MaintenanceCare and MaintenanceCare and MaintenanceTo keep your I5S operating properly, observe the following:

Remove the power pack before cleaning.

Use only a damp cloth and mild detergent for cleaning. Abrasives may damagethe display window.

Be careful not to scratch the display window.

Do not allow any liquid to flow inside the I5S.

Do not store long periods of time with the batteries installed.
