1. DESCRIPTION
The BA317E-SS is an intrinsically safe, one input Tachometer
housed in a rugged 316 stainless steel panel mounting enclosure,
which can operate with a wide range of sensors.
This abbreviated instruction sheet is intended to assist with
installation, a comprehensive instruction manual describing safety
certication, system design and conguration may be downloaded
from the BEKA website or may be requested from the BEKA sales
oce.
The BA317E-SS has IECEx, ATEX and UKEX intrinsic safety
certication for use in ammable gas and dust atmospheres. ETL
and cETL approval permits installation in the USA and Canada.
The certication information label, which is located on the top of
the instrument enclosure, shows the certication numbers and
codes. Other certications may be shown. Copies of certicates
may be downloaded from the BEKA website.
Typical certication information label
Other approvals may be shown
Special conditions for safe use
The IECEx, ATEX and UKEX intrinsic safety certicate numbers
have an ‘X’ sux indicating that for some applications special
conditions apply for safe use.
a. When installed in an Ex e, Ex p or Ex t panel enclosure
all connections to the BA317E-SS must be made by
appropriately rated Zener barriers or galvanic isolators.
This means that when installed in an Ex e, Ex p or Ex t panel
enclosure the BA317E-SS remains an intrinsically safe instrument.
b. The front of the stainless steel enclosure complies with the
requirements for Ex e, Ex p & Ex t type of protection.
Therefore when correctly installed the BA317E-SS Tachometer will
not invalidate the Ex e, Ex p or Ex t panel enclosure certication.
Use in combustible dust atmospheres
See full instruction manual for installation information
requirements and special conditions for safe use in combustible
dust atmospheres.

Scale card
The Tachometer’s units of measurement are shown on a printed
scale card visible through a window at the right hand side of
the display. The scale card is mounted on a exible strip that is
inserted into a slot at the rear of the instrument as shown below

Fig 4 Inserting exible strip carrying scale
card into slot at the rear of Tachometer.
Thus the scale card can easily be changed without removing the
Tachometer from the panel or opening the instrument enclosure.
New Tachometers are supplied with a printed scale card showing
the requested units of measurement, if this information is not
supplied when the instrument is ordered a blank card will be tted.
A pack of self-adhesive scale cards printed with common units of
measurement is available as an accessory from BEKA associates.
Custom printed scale cards can also be supplied.
To change a scale card, unclip the protruding end of the exible
strip by gently pushing it upwards and pulling it out of the enclosure.
Peel the existing scale card from the exible strip and replace it with
a new printed card, which should be aligned as shown below. Do
not t a new scale card on top of an existing card.
Align the self-adhesive printed scale
card onto the exible strip and insert
the strip into the Tachometer as
shown.

3. OPERATION
The Tachometer is controlled by four front panel push buttons.
When in the operating mode they have the following functions:
( + ) Access to conguration menu.
& + * If the Local Run-time reset function CLr tot in the
instrument conguration menu is enabled, operating
the & and * buttons simultaneously for more than 3
seconds resets the run-time display to zero.
) + * Run-time grand total.
If buttons are pressed for ten seconds or longer grand
total run-time is reset to zero. This is a congurable
function.
( + & Shows in succession, rmware version number,
instrument function tacho and any output accessories
that are tted:
- A Dual Alarm Outputs
- P Pulse output
- C 4/20mA output.
( + * When optional alarms are tted provides direct access
to the alarm setpoints if A5CP (access to setpoints) has
been enabled in the conguration menu.

4. CONFIGURATION
Tachometers are supplied configured as requested at time of ordering, if not specified default configuration will be supplied but can easily be changed on-site.
Fig 6 shows the location of each function within the configuration menu with a brief summary of the function. Please refer to the full instruction manual for detailed configuration information and for
description of the optional outputs.
Access to the configuration menu is obtained by pressing the ( and ) buttons simultaneously. If the Tachometer's security code is set to default 0000 the first parameter input will be displayed. If
the instrument is protected by a security code, code will be displayed. The four digit code must be entered to gain access to the menu.
