BEKA BA588E is a general-purpose panel-mounting rate totalizer designed to work with various flowmeters. It features a dual-input configuration, allowing you to connect two flowmeters and display their outputs simultaneously. The device can perform calculations like summation or subtraction of the flow rates, depending on your configuration.

The BA588E provides a clear and customizable display, showing the flow rates and totals. You can easily change the measurement units using the included scale cards or create custom ones. The totalizer offers alarm outputs and 4/20mA output options for integration with external systems.

1. DESCRIPTION
The BA588E is a two input, general purpose panel mounting Rate
Totaliser which can operate with a wide variety of pulse output
owmeters. The instrument can display the output from each
owmeter and, depending upon how it has been congured, the
sum or difference between them.
This abbreviated instruction sheet is intended to assist with
installation, a comprehensive instruction manual describing
system design and conguration may be downloaded from the
BEKA website or may be requested from the BEKA sales ofce.
2. INSTALLATION
The BA588E Rate Totaliser has IP66 front of panel protection
but it should be shielded from direct sunlight and severe weather
conditions. The rear of the instrument has IP20 protection.
Cut-out dimensions
Recommended for all installations. Mandatory to achieve IP66
seal between instrument and panel.

Scale card
The Rate Totalisers 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

card into slot at the rear of Rate Totaliser.
Thus the scale card can easily be changed without removing the
Rate Totaliser from the panel or opening the instrument enclosure.
New Rate Totalisers are supplied with a printed scale card showing
the requested units of measurement, if this information is not
supplied when the Rate Totaliser 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 Rate Totaliser as
shown.

The BA588E is CE marked to show compliance with the
EMC Directive 2014/30/EU.
4. CONFIGURATION
Rate Totalisers 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
lineariser and optional outputs.
Access to the configuration menu is obtained by pressing the ( and ) buttons simultaneously. If the Rate Totaliser's security code is set to default 0000 the first parameter function 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.
