1 Preface
Please read this instruction manual
carefully before installation and start-up.
Please observe all warnings and
advice, both for your own safety and for
general plant safety. If the device is not
used in accordance with this instruction
manual, then the intended protection
can be impaired.
2 Safety Instructions and
Warnings
Please use the device only if its
technical condition is perfect. It should
be used only for its intended purpose.
Please bear in mind safety aspects and
potential dangers and adhere to the
operating instructions at all times.
2.1 Use according to the intended
purpose
The preset counter 924 detects and measures
pulses, times and frequencies up to max. 60 kHz
and offers a wide variety of different operating
modes. At the same time, the preset counter
processes programmed presets. Use for any
purpose over and beyond this will be deemed as
not in accordance with its intended purpose and
thus not complying with the requirements.
The application area for this device lies in industrial
processes and controls, in the fields of
manufacturing lines for the metal, wood, plastics,
paper, glass, textile and other like industries. Over-
voltages at the terminals of the device must be kept
within the limits of Over-voltage Category II.
The device must only be operated when mounted
in a panel in the correct way and in accordance
with the section “Technical Data”.
Correct operation of the device requires the
mandatory use of the appropriate external safety
fuse. Advice concerning the recommended fuse-
protection can be found under “Technical Data”.
The device is not suitable for use in hazardous
areas and for areas excluded in EN 61010 Part 1.
If the device is used to monitor machines or
processes in which, in the event of a failure of the
device or an error made by the operator, there
might be the risk of damaging the machine or
causing an accident to the operators, then it is your
responsibility to take the appropriate safety
measures.
2.2 Mounting in a control panel
CAUTION
Mount the device away from heat
sources and avoid direct contact
with corrosive liquids, hot steam or
similar.
Mounting instructions
1. Remove mounting clip from the device.
2. Insert the device from the front into the panel
cut-out, ensuring the front-panel gasket is
correctly seated.
3. Slide the fixing clip from the rear onto the
housing, until the spring clamps are under
tension and the upper and lower latching lugs
have snapped into place.
2.3 Electrical Installation
DANGER
The device must be disconnected
from the power supply, before any
installation or maintenance work is
carried out. AC-powered devices
must only be connected to the low-
voltage network via a switch or
circuit breaker.
Installation or maintenance work
must only be carried out by qualified
personnel.
Advice on noise immunity
All connections are protected against external
sources of interference. The installation location
should be chosen so that inductive or capacitive
interference does not affect the device or its
connecting lines! Interference ( e.g. from switch-
mode power supplies, motors, clocked controllers
or contactors) can be reduced by means of
appropriate cable routing and wiring.
Measures to be taken:
Use only shielded cable for signal and control lines.
Connect cable shield at both ends.
The conductor cross-section of the cables should
be a minimum of 0.4 mm².
The shield connection to the equipotential bonding
should be as short as possible and with a contact
area as large as possible (low-impedance).
Only connect the shields to the control panel, if the
latter is also earthed.
Install the device as far away as possible from
noise-containing cables.
Avoid routing signal or control cables parallel to
power lines.
Cables and their insulation should be in accordance
with the intended temperature and voltage ranges.

Stop: Edge to Inp B
Start: 1. Edge to Inp B
Stop: 2. Edge to Inp B
Timing can only be controlled via
the Gate input
Inp A and Inp B: no function
The timer is reset by means of a
RESET (to zero when adding, to
preset 2 when subtracting) and
then starts timing again.
Timing is stopped with adding
operations when preset 2 is
reached.
Timing is stopped with
subtracting operations when zero
is reached.
A RESET during the timing
process also causes this to stop.
Inp A and Inp B: no function.
Gate control for Timing
Timing takes place when the
Gate input is not active.
Timing takes place when the
Gate input is active
User input
When the MPI input is activated
the display is “frozen” and
remains “frozen” until the MPI
input is deactivated.
Internally the preset timer
continues counting.
When the MPI input is activated
the current count value for the
preset that has just been
selected will be adopted as the
new preset value.

When the MPI input is activated
the preset timer will be set to the
value specified in the parameter
SEtPt. See also 7.10

7.9 Setting the presets
7.9.1 Setting via Decade Keys
In programming mode Preset 2 will always be
displayed in the lower line. This is except for the
output operations AddBat, SubBat,AddTot and
SubTot.
Press the Prog/Mode key until
the preset to be changed is
displayed - or .
Press any decade key
ÖDisplay switches to the editor mode
Set the desired preset value
using the decade keys
Press the Prog/Mode key to
confirm the value and save it
ÖDisplay switches to the editor mode of the
next preset or
Approx. 3 s after the last press of
the decade keys or by pressing
the Reset key the new preset
value will be accepted and the
counter will switch back to
operating mode.
7.9.2 Setting with Teach-In Function
Program the MPI input to tEAch
In programming mode, select the
preset to be changed using the
Prog/Mode key
Briefly activate the MPI (NPN or PNP input logic)
ÖThe current count value will be adopted as
the new preset value
The preset value can subsequently be
further modified via the decade keypad.
7.9.3 Setting the tracking presets (trail)
If a tracking preset has been programmed, the
value for Preset 2 can be set either via the decade
keypad or via the Teach-IN function.
However the value for Preset 1 must be entered via
the decade keypad. In this instance, it is not
possible to use the Teach-In function.
7.10 Set Function
Both the pulse counter and the timer can be set to
a default value by means of the Set function.
Programme the MPI input to SEt
Set menu item SEtPt to the
desired value
Briefly activate the MPI (NPN or PNP input logic)
ÖFor add. output operations the pulse
counter or timer will be set to the SEtPt
default value
ÖFor sub. output operations the pulse
counter or timer will be set to the
difference between the value of Preset 2
and the value of SEtPt .
