BEKA BA317E Tachometer Instruction Manual
1. DESCRIPTION
The BA317E and BA318E are panel mounting, intrinsically safe, one input Tachometers which will function with a wide variety of sensors. The instruments display speed plus the run-time of the machinery being monitored.
The two models are electrically similar, but have different size displays and enclosures.
This abbreviated instruction sheet is intended to assist with installation, a comprehensive instruction manual describing safety certification, system design and configuration may be downloaded from the BEKA website or may be requested from the BEKA sales office.
Both models have IECEx, ATEX and UKEX intrinsic safety
certification for use in flammable gas atmospheres. ETL and cETL approval
permits installation in the USA and Canada. The certification information
label, which is located on the top of the instrument enclosure, shows the
certification number and codes. Other certifications may be shown. Copies of
certificates may be down loaded from the BEKA website.
Typical certification information label
Special conditions for safe use The IECEx, ATEX and UKEX certificates have an `X’ suffix indicating that special conditions apply for safe use.
WARNING To avoid an electrostatic charge being generated instrument enclosure should only be cleaned with a damp cloth.
2. INSTALLATION
Both models have IP66 front of panel protection but they should be shielded from direct sunlight and severe weather conditions. The rear of both models have IP20 protection.
Cut-out dimensions Recommended for all installations. Mandatory to achieve IP66 seal between instrument and panel.

EMC
For specified immunity all wiring should be in screened twisted pairs with
screens earthed at one point within the safe area.
Scale card
The Tachometers 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 flexible strip that is inserted into a slot at the rear of the
instrument as shown below
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 fitted. 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 flexible strip by gently pushing it upwards and pulling it out of the enclosure. Peel the existing scale card from the flexible strip and replace it with a new printed card, which should be aligned as shown below. Do not fit a new scale card on top of an existing card.
3. OPERATION
The Tachometers are controlled by four front panel push buttons. When in operating mode they have the following functions:
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.
Unless otherwise specified menu functions are shown on the upper display
