Preliminary Warnings
The following preliminary warnings should be
read before installing and using the series 40B
96 interceptor . This will allow the controller to
be put into service more quickly and will avoid
certain problems which may mistakenly be interpreted as malfunctions or limitations of the interceptor.
• Immediately after unpacking the controller, make a
note of the order code and the other identification data
given on the label affixed to the outside of the container
and copy them to the table below.
These details must always be kept close at hand and
referred to the personnel involved in the event of help
from Gefran Customer Service Assistance.
• Check also that the controller is complete and has
not been damaged at all during transit, and that the
package contains not only the instrument and these
Instructions for Use, but also the two brackets for
fixing to the panel and the dust protection seal - see:
Installation with Panel Fixing in Section 2.
Any inconsistencies, omissions or evident signs of
damage should be reported immediately to your
Gefran sales agent.
• Check that the order code corresponds with the
configuration requested for the application the
controller is needed for, referring to Section 7:
“Technical - Commercial Information”.
• No. and Type of Inputs/Outputs available
• Presence of the necessary options and
accessories

2 • INSTALLATION AND CONNECTION
This section contains the instructions necessary
for correct installation of the 40B96 instrument
into the machine control panel or the host
system and for correct connection of the interceptor power supply, inputs, outputs and interfaces.
Before proceeding with installation read the
following warnings carefully!
Remember that lack of observation of these
warnings could lead to problems of electrical
safety and electromagnetic compatibility, as
well as invalidating the warranty.
Electrical power supply
• the instrument is NOT equipped with an On/Off switch:
the user must provide a two-phase disconnecting switch
that conforms to the required safety standards (CE marking), to cut off the power supply upstream of the instrument.
The switch must be located in the immediate vicinity of
the instrument and must be within easy reach of the operator.
One switch may control more than one instrument.
• if the instrument is connected to NOT isolated electrical equipment (e.g. thermocouples), the earth connection must be made with a specific conductor to prevent
the connection itself from coming directly through the
machine structure.
• if the instrument is used in applications with risk of
damage to persons, machinery or materials, it is essential to connect it up to auxiliary alarm equipment.
It is advisable to make sure that alarm signals are also
triggered during normal operation.
The instrument must NOT be installed in flammable or
explosive environments; it may be connected to equipment operating in such atmospheres only by means of
appropriate and adequate types of interface, conforming
to the applicable safety standards.

Advice for Correct Installation for EMC
Instrument power supply
• The power supply to the electronic equipment on the
switchboards must always come directly from an
isolation device with a fuse for the instrument part.
• The electronic instruments and electromechanical
power devices such as relays, contactors, solenoid
valves, etc., must always be powered by separate
lines.
• When the electronic instrument power supply is
strongly disturbed by the commutation of transistor or
power units or motors, an isolation transformer
should be used for the controllers only, earthing the
screen.
• It is essential that the plant has a good earth
connection:
- the voltage between neutral and earth must not be <1V
- the Ohmic resistance must be <6Ω;
• If the mains voltage fluctuates strongly, use a voltage
stabilizer.
• In the proximity of high frequency generators or arc
welders, use adequate mains filters.
• The power supply lines must be separate from the
instrument input and output ones.
Inputs and outputs connection
• The externally connected circuits must be doubly
isolated.
• To connect the analogue inputs the following is
necessary:
- physically separate the input cables from those of the
power supply, the outputs and the power connections.
- use woven and screened cables, with the screen
earthed in one point only
• To connect the regulating and alarm outputs
(contactors, solenoid valves, motors, fans, etc.), fit
RC groups (resistance and condensers in series) in
parallel to the inductive loads that operate in
Alternating Current.
(Note: all the condensers must conform to VDE
(class X2) standards and withstand a voltage of at
least 220V AC. The resistances must be at least 2W).
• Fit a 1N4007 diode in parallel with the coil of the
inductive loads that operate in Direct Current.
GEFRAN S.p.A. declines all responsibility for
any damage to persons or property caused
by tampering, neglect, improper use or any
use which does not conform to the characte-
ristics of the instrument and to the indica-
tions given in these Instructions for Use.
Dimensions and cut-out
Installation with panel mounting
As well as the actual instrument and these instructions
for use, the package also contains:
• 2 panel fixing brackets (A)
• 1 protective seal against dust and water spray ( B)
Fit the instrument to the panel as shown in the figure.
Warnings and instructions for mounting to the panel
Instructions for installation category II,
pollution level 2, double isolation.
• only for low power supply: supply from Class 2 or
low voltage limited energy source.
• the power supply lines must be separate from the
controller input and output ones
• group the instruments together keeping them
separate from the powered part of the relay
• do not install high-power remote switches,
contactors, relays, thyristor power units (especially
the "phase angle" type), motors, etc. in the same
switchboard
• avoid dust, humidity, corrosive gasses and heat
sources
• do not block the ventilation holes: the working
temperature must be between 0...50°C
• surrounding air: 50°C
• use 60/75°C copper (Cu) conductor only, wire size
range 2x No 22 - 14AWG, Solid/Stranded
• use terminal tightening torque 0.5N m
Nominal ambient conditions

4 • CONFIGURATION / PROGRAMMING
This section contains the instructions necessary to
configure the instrument according to the needs of the
application..
Optimal working operation of the 40B96 in the field of application it is intended for depends largely on correct configuration
and programming of the relevant control parameters.
The flexibility and high performance level of these instruments
is in fact based on the numerous parameters that can be
programmed directly by the user with the buttons on the control
panel, or transferred from a PC, in the form of configuration
files, by means of the RS485 interface available as an option.
Configuration
Access to all the configuration / programming menus and to all
the parameters available in configuration, allows every detail of
the Controller to be configured, to satisfy all application requirements.
Correct setting of the parameters involved in the
configuration presumes a high level of knowledge
regarding of use problems and techniques, and so it
is recommended that these parameters are not changed unless the user is fully aware of the consequences, that could arise form incorrect settings.
It is the user's responsibility to check that the
parameters are set correctly before putting the
instrument into service, in order to avoid damage
to persons or property.
The following pages describe one by one the various menus
and show for each parameter the concise description of the
function performed, any default values and the range of values
that can be set.
Supplementary notes on consulting the Configuration/
Programming pages
To set some particularly complex parameters certain tables or
detailed explanatory notes must be referred to.
These tables or explanatory notes are shown directly on the
right of the page next to the parameter in question.
Application notes
The detailed explanations of certain functioning modes
or special techniques the result Gefran's lengthy
experience in the field of temperature control are instead
contained at the end of the Configuration/Programming
Section and can represent a valuable reference tool for
the user.
Where necessary, in the configuration / programming
flows the appropriate referrals to these Application
Notes are provided.
Password:
PPAA
When scrolling through the menu (keeping pressed down),
following the 0V menu, the word PA appears.
Access to the next menus is only possible if the PA = 99, parameter is set to 99 by pressing .
Having set the value to 99, press and keep it pressed
down to access the next menus.
Protection code:
PPRR
The PR parameter is used to enable or disable the display
and/or the possibility of editing certain parameters. For further
details refer to the description of the PR parameter in the configuration flows.
Jumper S4 on CPU Board
The absence of jumper S4 on the CPU board of the instrument
prevents access to all the menus when the hardware
configuration of the instrument does not require the pre-set
parameters to be changed.
This jumper is engaged or disengaged during production and
normally does not need to be modified by the final user.
For further information, refer to Section 6 - Maintenance.

and return to normal display
Note 2
If you configure the "direct access to parameter
o.F" function (offset correction of display) with
parameters t.U. = 19 (t.d.=19), the calibration
procedure is as follows:
- keep the raise (lower) key pressed until you
see o.F.
- when the F key is released, the display will
alternate between o.F and the previously set
o.F value.
- set the offset value you want by means of the
raise/lower keys.
- keep the F key pressed to exit the procedure
and return to normal display.

Application Notes
Eb Function
The standard device is produced with parameter C.I.= 8,
with sampling time of 120 msec and Eb function disabled.
The Eb function lets you detect if the probe power supply is interrupted. This function is valid for probe currents >
20mA (8mA in version 2.0x)
Example:
- probe voltage 10V
- strain-gauge resistance 350Ω
V 10
- current = = ≅ 28mA
R 350
or for three probes connected in parallel
- probe voltage 10V
- strain-gauge resistance 350Ω

HOLD function
The input value and alarms are frozen while the logic input is active.
With the logic input active, a reset turns OFF both the relay outputs and the alarms latch.
FLASH function
Input value is sampled; state of alarms is not transferred to outputs; outputs are “frozen”.
When the logic input is active the input value is “frozen” and the outputs are updated according to the calculated
alarms state, including the ones latched.

UCAL: strain-gauge calibration
a) Positive signal polarization
Suppose we test a probe (load cell) with sensitivity of 2mV/V , powered at 10V.
The input signal range is 0 to 20mV. From unloaded to loaded cell you should see a value from 0 to 1000.
Set scale limits: L.S. = 0; H.S. = 1000. Calibration procedure: U.C. = 3.
Phase F1: unload the cell (equal to applying input voltage of 0mV). W ait 2 seconds for the signal to stabilize. Press key F.
Phase F2: load the cell with a sample weight: for example, 80% of total weight (equal to applying input voltage of 80% of 20mV
(2mV*10V) = 16mV). On display, set a value equal to 80% of H.S. = 800.
Press key F.
Phase F3: unload the cell (equal to applying input voltage of 0mV). W ait 2 seconds for the signal to stabilize. Press key F
(calibration finished).
b) Suppose we test a probe (force sensor) with sensitivity of 2mV/V , powered at 10V.
The input signal range is -20mV to 20mV. From maximum compression to maximum traction you should see a value
from -1000 to 1000. Set scale limits: L.S. = -1000; H.S. = 1000.
Calibration procedure: U.C. = 4.
Phase F1: do not apply any traction or compression to the sensor (equal to applying input voltage of 0mV).
Wait 2 seconds for the signal to stabilize. Press key F .
Phase F2: apply compression equal to 80% of total compression
(equal to applying input voltage of 80% of 20mV (2mV*10V) = 16mV). On display , set a value equal to 80% of H.S. = 800.
Press key F.
Phase F3: do not apply any traction or compression to the sensor (equal to applying input voltage of 0mV).
Wait 2 seconds for the signal to stabilize. Press key F (calibration finished).

Virtual Instrument
Management of the virtual instrument via serial is activated with the Pr parameter .
By setting the S.I, S.o and S.U parameters, you can enable writing of a few variables from the serial line to set
input values, output state, LED state, and the value shown on displays.
You have to enable alarm limits when the write operations are continuous and you don’t have to keep the last
value in EPROM (applications requiring continuous variations of interceptions).
Enabling the PV input lets you exclude local acquisition of the input, replacing it with the value written in the
VALUE_F register.
Enabling digital input lets you set the state of this input, for example, to perform the zero setting with writing of the
appropriate bit in the V_IN_OUT register.
In analog mode, you can set the ON/OFF state of outputs OUT1, ..., OUT4 by writing the bit in the V_IN_OUT
register; the value of analog output OUTW in the V ALUE_W register; the state of LEDs OUT1,..., OUT4 by means
of the bits in the V_X_LEDS register.
* To use the Display resources for setting a value on the display and Keyboard to simulate key pressure, you also
have to set bit 7 of the STATUS6_W register (Modbus address 345 / Cencal 690). This bit is reset at every
power-up.

6 • MAINTENANCE
This section gives the information and the necessary
warnings for routine maintenance of the instrument
and contains a Troubleshooting Guide which should
be read before seeking help from the Gefran
Customer Service Assistance, in the event of instrument malfunction.
If installed and configured correctly according to the
instructions and the recommendations provided in Sections 2
and 4 of these Instructions for use, the instrument will work
normally without any need for maintenance, apart from the
usual operations of cleaning the faceplate, and if necessary
the internal parts of the instrument.
To gain access to the inside of the instrument (for
example for cleaning or to check the jumpers)
just undo the screw at the bottom of the faceplate
and take out the instrument without having to
disconnect the cables.
Make sure that the power is turned off upstream
of the instrument however.
Remember that the 40B96 interceptor is not
equipped with an ON/OFF switch.
Cleaning the Instrument
To clean the faceplate and the case use only a
cloth dampened in water or ethyl alcohol.
Do not use hydrocarbon-based solvents
(trichiorethylene, petrol, etc.).
Do not use compressed air to remove dust from the electronic circuit boards, if necessary use a clean brush with
soft bristles.
Repairs
Repairs to the 40B96 instrument must only be
carried out by qualified technicians, properly trained and authorized by Gefran. Any attempts at
repair or modification of the instrument hardware
characteristics by unauthorized personnel will
invalidate the warrantya.
Checking the jumpers
The solders side of the CPU board contains the jumper S4
which enables (if on) access to the controller menus.
The instrument contains components which are
sensitive to electrostatic discharge, so the
relevant precautions must be taken when
handling the electronic circuit boards contained
in it, in order to avoid permanent damage to
components themselves.

This operation must be done by trained technical personnel.
Example in case of relay output:
- Direct mode: energized relay and related closed contact correspond to active trip point.
- Reverse mode: de-energized relay and related open contact correspond to active trip point.

This section contains information regarding the instrument order codes and the main accessories available.
As stated in the Preliminary Warnings of these Instructions for Use, correct interpretation of the instrument order
code allows the hardware configuration to be identified immediately and so it is essential to quote the order code
each time the Gefran Customer Care Service is contacted for assistance with any problems.
Order code – 40B96 alarm unit
For information on the availability of codes please contact your Gefran dealer .

The characters shown on the
display are incomplete or

Instrument power supply problem. Check that power is being supplied to terminals 10-1 1.
make sure the power supply corresponds with the one stated in the order code:
40B96 5 xx – xx – xx – x.x – 1 = 100..240V ac/dc
40B96 5 xx – xx – xx – x.x – 0 = 1 1..27Vac/dc
Possible fault with one of the display segments. Check that all the segments are working properly by switching the instrument off and then on again. When it is switched on again a selfdiagnostic test is performed that checks intermittent start up of all the segments (displays the
value 8888). If one or more segments do not light up contact your Gefran dealer .
If the problem appears during the first installation, it probably means that the hardware
configuration doesn't allow changing of the default parameters beyond the alarm setpoint
value. (Parameter change is enabled by jumper S4 on the CPU board). If on the other hand
the problem occurs on a instrument that previously gave access to the configuration
parameters, this probably means that there is a false contact on the jumper S4.
In this case check the continuity of the jumper referring to the previous paragraph.
Access to some menus and/or parameters is protected by a password (P A) and a code (PR)
that limits configuration mode.
To set the password and the protection code correctly refer to Section 4
"Configuration/Programming”.
In the first four cases it means that an input error has been found (for details refer to Section 3
- Functions).
In the last case, it means probe power supply failure.
This function has to be enabled via parameter c.I. on the In menu.
