User manual for electronic preset counter SLN-44
2.
GENERAL CHARACTERISTICS
is a DIN 48 x 48 mm electronic preset counter with a Blue STN LCD display
with white backlight. The display is 6 digits dual layer display divided into: main display and
sub-display. The main display has a 10.0 x 5.0 mm figure size showing the count value and
the sub-display shows the preset values. Included in the display are preset level indicators and
output indicators which can be toggled by a push of a button.
is available in 1 or 2 level preset type which makes it an ideal counter for
general counting or total/batching counting applications. It is 100 - 240V AC or 12-24V DC
powered and has an external power supply of 12V DC for sensors. The
bidirectional (Quadrature), Add, Subtract or Add/Subtract and upon reaching the preset
value/s, the built-in output relays are actuated.
Functional modes, operation modes and output modes are fully programmable with the
menu driven display using the front panel buttons. Functional modes includes: count speed
(upto 10 kHz), input signal (contact / open collector or voltage), prescale, decimal point
position, key protection and free write. It has a built-in EEPROM memory to avoid loss of count
during sudden power cut. The front panel protection is IP 54. Wiring connections is secured
with the terminal screws.
the most versatile and functional preset counter even for the
complicated applications such as packaging (batching), converting (prescale), cut-to-length
and many more.
