5. The digital display shall only operated if it has
been correctly mounted in a panel, in accordance with the chapter “Main technical features”.
1.3 Use according to the intended purpose
The digital display may be used only as a panelmounted device. Applications of this product may
be found in industrial processes and controls, in
manufacturing lines for the metal, wood, plastics,
paper, glass, textile and other processing industries. Over-voltages at the terminals of the digital
display must be kept within the limits in Category II
If the digital display is used to monitor machines
or processes in which, in case of a failure of the
device or an error made by the operator, there
might be risks of damaging the machine or causing accidents to the operators, it is your responsibility to take appropriate safety measures.
1.4 Description
CODIX 52U is a multipurpose device. Depend-
ing on the pr ogrammed basic function, the
device operates like
• an electronic totaliser and frequency meter
(see page 2)
• an electronic display counter with
2 totalising ranges (see page 4)
• an electronic totaliser and time meter
(see page 6)
• an electronic time meter with 2 time ranges
(see page 9)
2. Setting of the operating parameters
a. Press both front side keys keys and switch
on the supply voltage or, if the supply voltage
is already on, press both keys simultaneously
during 5 s.
b. The display shows
c. After releasing the keys, the display shows
c1. Hold the left key pressed an d press the right
key to leave the programming operation.
c2. Press the right key to switch to
d. Hold the left key pressed an d press the right
key to switch to the first parameter.
e. After releasing the keys, the display alter nates
between the menu title and the current menu
item setting. After pressing any key, only the
menu item setting is displayed.
f. Pressing the right key, the menu item setting
will be switched to the next value. If figures
are to be input (e.g. when setting the scaling
factor), select first the decade using the l eft
key, and then set the value using the right key.

Electronic totaliser and time meter
Codix 52U: basic o perating mode
1. Description
• 6 digit totaliser and time meter with Reset function
• Red LED display, character hei ght 8 mm
• Display range 0 ... 999 999
• Leading zeros suppression
• Programming via two setting keys on the front
side
• During programming, the display guides the
user with text pr ompts
• Operation indicator: th e decimal point of the
lowest digit blinks while the count is active.
• Time meter operating modes:
– Counting while INP B is inactive “GAtE.Lo”
– Counting while INP B is active “GAtE.hi”
– Count Start/Stop with INP B edge B “Inb.Inb”
• Counting ranges: h; min; s; h.min.s
2. Inputs
INP A
Dynamic count input for the totaliser.
INP B
Start-/Stop or gate input for time meter
(independent of the input mode)
RESET
Dynamic RESET input. Linked in parallel to the
red RESET key. Sets the counter to zero. Can
be adjusted individually for the totaliser and the
time meter.
3. Selection of the displayed value
Pressing the r ight key allows switching between
the totaliser display and the time met er display
. Press the key briefly to display for 2 seconds
the current function (“total” or “time”). If, during
this period of time, the right key is pressed a
second time, the device switches to the next
function and displays a confirmation (“total” or
“time”) for 2 seconds. Then, the value of the
selected function is displayed.
4. Programming routine
The programmable parameters of the device
are described below, in the order in which they
can be set. The device is fully programmed
after one pass of the routine.
The first values stated correspond to the
factory settinfs
