KELLER ECO2-Ei Intrinsically Safe Digital Manometer Instruction Manual

KELLER ECO2-Ei Intrinsically Safe Digital Manometer Instruction

ECO2-Ei Digital Manometer with Min.-/Max.-Display.

Description

Digital manometer with Min.-/Max.- pressure indication.
The technical data of the digital manometer can be taken from the corresponding data sheet or from the agreed specifications.

Turn-On and Functions

ECO2-Ei has two operating keys. The left key (SELECT) serves to select the functions and the pressure units. The right key (ENTER) activates the selected function or pressure unit. The right key is also used to switch between the Min.- and Max.- pressure value.

Turn-on:
Pressing the SELECT key turns the instrument on. The instru-ment first displays the full-scale pressure range (top display) and the software version (year/week). The instrument is then ready for use and indicates the actual pressure (top display) and the last measured Max. pressure value (bottom display).
The instrument has the following functions:

RESET
Min.-/Max.-value are set to the actual pressure.
OFF:
Turns off the instrument.
MANO:
Releases the following func-tions:
ZERO SET:
Sets a new pressure zero reference.
ZERO RES:
Sets the pressure zero to factory setting.
CONT on:
Deactivates the automatic turn-off function.
OR
CONT off:
Activates the automatic turn-off function (the instrument turns off 15 minutes after the last key operation), …followed by the unit selec-tion: bar, mbar, hPa, kPa, MPa, PSI, kp/cm2

Example: Setting a new pressure unit (mbar):

• Turn on the instrument by shortly pressing SELECT.
• Wait for the instrument’s measuring mode (≈ 3 s).
• Press the SELECT-key 3 times: MANO appears.
• Press ENTER: ZERO SEt appears.
• Press SELECT: ZERO rES appears.
• Press SELECT: CONT on or CONT off appears.
• Press SELECT: bar ap-pears.
• Press SELECT: mbar ap- pears.
• Press ENTER: The new pressure unit (mbar) is set. The instrument returns to the measuring mode.

Display of the Minimum Value
When in the measuring mode (Display: Actual Pressure and Max. pressure value), you may display the Min. pressure value for 5 seconds by shortly pressing the ENTER-key.
Notes

1. The functions and units can also be called up by keeping the SELECT-key depressed. Releasing the key enables the displayed function or unit to be activated with the ENTER-key.
2. If the selected function or unit is not activated within 5 seconds with the ENTER-key, ECO2-Ei returns to the measuring mode without changing any settings.
3. Turning ECO2-Ei on and off does not influence any of the previous settings.
4. If the CONT on function is activated, it is indicated with a flashing sign on the display (OFF flashes when CONT on is set).
5. If a pressure can not be represented on the display, OFL (overflow) or UFL (underflow) appears on the display.
6. If the actual pressure goes beyond the measuring range, the last valid pressure value starts flashing on the display (overload warning).
7. Temperatures outside of 0…50 °C could impair the readability of the display.

Installation

• The installation must be carried out by qualified personnel only.
• ECO2-Ei has 7/16”-20 UNF male thread and is delivered com-plete with an O-ring seal swivel fitting which allows ECO2-Ei to be rotated 360°.
• Only minimal torque is need-ed to seal up to 700 bar. Process pressure connection is G1/4” male.
• The swivel adapter can be tightened with a max. torque of 50 Nm.

Battery Change / Battery Life

• When the battery starts weak-ening, a low battery warning (BAT LOW) will appear in the display. Battery change:
• Open the battery compartment and change the battery (type Renata CR 2430).
• When reassembling, make sure that the O-ring remains imbed-ded in the cover.
• The battery life is approxima-tely 1000 hours at continuous operation.
• Please use a coin for opening the battery box to prevent da-mage to the battery cover. Dispose of discharged batteries properly, where they are to be picked up by a qualified waste management company. Place replacement battery between the contact springs, paying atten tion to the polarity (positive pole facing up). Close the cover plate by hand, if possible.

Ranges / Calibration

• The ZERO-function allows to set any pressure value as a zero reference.
• The factory setting of the pres-sure zero for the ranges ≤ 61 bar absolute is at vacuum (0 bar absolute). For relative pressure measurements, activate “ZERO SEt” at ambient pressure.
• Instruments > 61 bar absolute are calibrated with the zero at atmospheric pressure.

General Safety Instructions

• When installing and operating the digital manometer, attention should be paid to the correspon-ding safety regulations.
• Only mount the digital mano-meter onto unpressurized sys-tems.
• On pressure ranges ≥ 61 bar, the pressure connections could show residual hydraulic oil.
• Please also note the correspon-ding data sheet.

Special Conditions for Safe Use

• The digital manometer ECO2-Ei is an “intrinsically safe appara-tus”; it can be operated in explo-sive atmospheres. The operating ambient temperature are inclu-ded between -10 °C and +80 °C. Connect the pressure port of the digital Manometer to neutral earth (to ground).
• The following battery type must be used in explosive atmos-pheres: Renata CR 2430. The battery may be changed inside the zone with a potentially ex-plosive atmosphere.
• Do not conduct such processes in close proximity, which gene-rate charged particles (air ioniser, high-voltage electrodes, etc).
• Increases the maximum media temperature at the transducer 80 °C it is the duty of the final user to make own safety clarifi-cations.
