ter/power limiter.
The instrument used as a timer offers the possibility to
program: up to 3 timings (Set point), 6 operating modes for
OUT1 output, 10 operating modes for OUT2 output, 4 time
scales (which allow a count from a maximum of 9999 hours
to a minimum of 0.01 seconds), 6 counting enabling func-
tioning modes and 2 counting modes (UP or DOWN).
The instrument used as a pulse counter offers the pos-
sibility to program: up to 2 Set points, 3 operating modes
for OUT1 output, 4 operating modes for OUT2 output and
offers the possibility of counting division.
Moreover, the instrument can also be used as a power
limiter by programming a duty-cycle from 0 ÷ 100% and a
total cycle time from 1 ÷ 900 s.
The upper 4-digit display normally shows the counting
status while the lower 4-digit display the selected timing
(set-point), the status of the outputs is shown by 2 LEDs.
The instrument has 1 counting/counting enabling input
(CNT) and 1 digital input with programmable operation
(RESET or reverse counting) whose signals can come from
free of voltage contacts, from devices with NPN or PNP
transistor output. It can have up to 2 relay outputs or for
driving Solid State Relays (SSR).

2. PROGRAMMING
2.1 Set Points (timings) programming
The normal programming mode of the delay times (Set
Times) occurs by pressing and releasing the key, the up-
per display starts showing s.t1 (if the instrument is working
as a Timer) or s.C1 (if the instrument is working as a Coun-
ter)and the lower display shows programmed value.
To change the value press the key to increase the number
shown or to decrease it. These 2 keys normally act in one
digit steps a time, but if kept pressed for more than 1 s the
value increases or decreases faster and after 2 more seconds
in the same condition, the speed further increases in order
to quickly reach the desired value. However, through t.edt
parameter (Timer) or t.EdC (Counter) it is possible to define
if and which Set Points can be set with the short key. A
further option provides the setting of S.T1 or s.t2 (Timer)/S.C1
or S.C2 (Counter) Set Point value only, using the / keys
without pressing in advance the key (t.Ed = 8/9).
t.ed parameter can assume a value between oF and 9:
oF No Set Point can be set with the short key (if pressed
and released, the key has no effect);
1 Only s.t1/ S.C1 Set Point can be set with this procedure;
2 Only s.t2/ S.C2 Set Point can be set with this procedure;
3 Both s.t1 and s.t2/ S.C1 and S.C2 Set Points can be set
with this procedure;
4 Only s.t3/ Str Set Point can be set with this procedure;
5 s.t1 and s.t3/ S.C1 and S.tr Set Points can be set with
this procedure;
6 s.t2 and s.t3/ S.C2 and S.tr Set Points can be set with
this procedure;
7 s.t1, s.t2 and s.t3 / S.C1 , S.C2 and S.tr Set Points can be set
with this procedure;
8 s.t1/ S.C1 Set Point value can be set directly using / ;
9 s.t2/ S.C2 Set Point value can be set directly using / .
For example, in case the parameter t.Edt or t.Edt = 1or 3,
the procedure is the following:
–Press and release the key, the display shows s.t1/ S.C1
alternated to its value.
–To change the Set Point, press the key to increase the
value or to decrease it.
–If tEd/t.Edt = 1 , once the desired value has been set,
press the button to exit the fast programming mode. If
tEd/t.Edt = 3 , pressing and releasing again the but-
ton the display shows S.t2/ S.C2 alternated to its value. To
change the value use the / keys as for the S.t1 value.
–Once the Set Point time has been programmed, press the
key to exit the Set Point programming mode.
To exit the fast Set Point programming mode press the
key after the last Set Point time has been displayed or press-
ing no buttons for about 10 s, after which the display returns
to normal operation.

2.2 Standard mode parameters setting
To access the instrument functionning parameters when
password protection is disabled, press the key for 5 s,
after which the display shows the code that identifies the first
programmable parameter, at this point use the / keys
to select the parameter that is to be changed, then press the
key, the upper display shows the parameter code and
the lower one its value that can be changed with the and
keys. Once the desired value has been set, press the
key again: the new value is stored and the upper display
shows only the code of the modified parameter.
Pressing the or keys, it is possible to select another pa-
rameter and change it as described. To exit the programming
mode, press no keys for about 30 s or keep the key pressed
for 2 s, the timer returns showing the actual count value.

2.3 Parameter protection using a password
The instrument has a parameter protection function using a
password that can be personalised through the t.PP parameter.
To protect the parameters, set the desired password number
at parameter t.PP and exit the programming mode.
When the protection is active, press the key for 5 s after
which the display shows r.p. Press the key again, the
display shows 0. Using / keys, insert the programmed
password number and press the key again.
If Password is correct the upper display shows the code of
the first programmable parameter. Now is possible to pro-
gram the instrument in the same way previously described.
Password protection can be disabled by setting t.PP = oF.

Notes: 1. All parameters are configured by default as “pro-
tected” so that by simply setting the t.PP param-
eter they are all protected by the Password.
2. If the Password gets lost, just switch OFF then
ON the instrument, push key during the initial
test keeping it pressed for 5 s. In this way it is
possible to access all the parameters, verify and
modify the parameter t.PP.
2.4 Customized mode parameter programming
(parameters programming level)
When activated, the password protection acts on all parame-
ters. If, once enabled the Password through the t.PP param-
eter, it is necessary to make certain parameters program-
mable without protection while keeping the protection on the
others, follow the procedure below:
–Enter the programming mode using the t.PP Password
and, with / keys, select the parameter that must be
accessible (not password protected).
–Once the parameter is selected, if the SET LED flashes,
the parameter is programmable only entering the pass-
word ( protected ). If SET LED is steady ON the parameter
is programmable without password ( unprotected ).
–To change the parameter visibility, press the key and,
keeping it pressed, press also the button.
–The SET LED changes its state indicating the new level
of the parameter accessibility (ON = Not protected ; Flash-
ing = Password protected ).
In case some parameters are set as Not protected, access-
ing the programming mode the display first shows the Not
protected parameters, then the r.p parameter through which
will be possible to access also the protected parameters.

2.5 Reset parameters to default value
The instrument allows to reset all parameters to those values
programmed in factory as default. To restore the default
parameters value, answer -48 to r.p password request.
Therefore, to make the reset to default parameters, enable
the Password protection using the t.PP parameter so that the
r.p setting is requested, at this point insert -48 instead of the
programmed access password. Once confirmed the pass-
word with the key the display shows “---” for 2 s, then the
instrument resets all the parameters to factory default setting.
2.6 Keyboard lock function
It is possible to completely lock the keyboard. This function
is useful when the controller is used in an accessible area
and unauthorized changes must be avoided.
To activate the keyboard lock, program the parameter t.Lo to
a value different from oF. The t.Lo value is the keys inactiv-
ity time after which the keyboard is automatically locked.
When the keyboard is locked, if any of the key is pressed, the
display shows L.n to indicate that the lock is active. To unlock
the keyboard, press contemporarily + keys and keep
them pressed for 5 s, after which the label LF appears on the
display and all the key functions will be available again.

3. USAGE WARNINGS
3.1 Allowed Usage
D The instrument has been projected as measure and
control device, built according to EN61812-1 for the
altitudes operation below 2000 ms.
Using the instrument for applications not expressly permitted
by the above mentioned rule must adopt all the necessary
protective measures.
The instrument must not be used in dangerous environ-
ments (flammable or explosive) without adequate protections.
D The installer must ensure that the EMC rules are
respected, also after the instrument installation, if
necessary using proper filters.
4. INSTALLATION WARNINGS
4.1 Mechanical Mounting
The instrument, in case 33 x 75 mm, is designed for flush-
in panel mounting. Make a hole 29 x 71 mm and insert the
instrument, fixing it with the provided special bracket(s).
To obtain the declared protection degree (IP65) the optional

4.2 Electrical connections
Carry out the electrical wiring by connecting only one wire to
each terminal, according to the following diagram, checking
that the power supply is the same as that indicated on the
instrument and that the load current absorption is no higher
than the maximum electricity current permitted.
As the instrument is built-in equipment with permanent con-
nection inside housing, it is not equipped with either switches
or internal devices to protect against current overloads: the
installation will include an overload protection and a two-
phase circuit-breaker, placed as near as possible to the in-
strument and located in a position that can easily be reached
by the user and marked as instrument disconnecting
device which interrupts the power supply to the equipment.
Further reccomendations:
–The supply of all the electrical circuits connected to the
instrument must be properly protected using devices (ex.
fuses) proportionate to the circulating currents;
–Use cables with proper insulation, according to the working
voltages and temperatures;
–Make sure that the input sensor cables are kept separate
from line voltage wiring in order to avoid induction of electro-
magnetic disturbances;
–If some cables are shielded, the protection shield must be
connected to ground at only one side;
–When the instrument has a 12 VAC/DC power supply (Order
Code a= F) it is recommended to use an external TCTR
transformer, or with equivalent features (class II insula-
tion) and to use only one transformer for each instrument
because there is no insulation between supply and input
D We recommend that a check should be made that the
parameters are those desired and that the application
functions correctly before connecting the outputs to
the actuators so as to avoid malfunctioning that may
cause irregularities in the plant that could cause dam-
age to people, things or animals.

5. OPERATING MODE
5.1 Operation selection as:
Timer, Pulse counter or Power limiter
Using parameter t.C it is possible to select the instrument’s
operating mode as Timer (t), as Counter (C) or as Power
limiter (P).
Depending on the value programmed for t.c parameter, the
instrument shows only the parameters related to the select-
ed operation mode (see the table of parameters).
As soon as this parameter is changed, the instrument resets
itself and goes into the new mode.
The selected mode is indicated by the switching ON of the
relative LED: (Timer), (Counter) or by the switch-
ing OFF of both LEDs (Power limiter).
5.2 Operation as a timer
5.2.1 Timer display operation
LED is used to indicate:
– Count in progress (flashing with 1 s period);
– Count enderd or stopped before the end (steady on);
– Reset status (OFF).
After Reset the display shows 0000 when counting mode is
UP (F.Cnt = uP) or the Set point value if the counting mode
is DOWN (F.Cnt = dn).
While counting, the display shows the time that elapses:
increasing if F.Cnt = uP or decreasing if F.Cnt = dn.
For functions that require a Cycle end (F.o1t = 1, 2), at the
end of the count the display shows: 0000 if F.Cnt = dn or the
Set point value if F.Cnt = uP.
At Count end, the Display flashes when parameter Endt = 0
or can be Steady ON when parameter Endt = 1.
The lower display instead shows the Set point value estab-
lished by the t.ddn parameter:
0 Active set point during counting;
1 S.t1;
2 S.t2;
3 S.t3.
If the back-up mode foresees the continuation of the count
even in the event of a power failure, the display is turned
OFF keeping only the LED flashing in order to limit the
battery absorption as much as possible.
5.2.2 Timer counting commands
Counting can be enabled/disabled using the -Start/Stop
key or via the (remote) digital inputs CNT and RST.
The operating mode of the -Start/Stop key is established
by parameters t.UFt and I.Fct, the operating mode of CNT
input is established by i.Fct parameter while the RST input
always acts as a Reset, i.e. blocks and resets the count
when it is activated and also has priority over the other com-
mands (while RST is active, the count cannot start).
The counting Start signal can therefore be given by the
-Start/Stop key, which normally has bistable (toggle)
operation, or via the CNT count enable digital input.
The operating mode of the CNT input can be programmed
using the i.Fct parameter to operate in different modes:
i.Fct = 1- Bistable Start/Stop
By activating the CNT input the count starts and it is
therefore possible to deactivate the input.
Activating CNT again, the count stops on the value reached
(without disabling the output if it was activate), the next
CNT impulse resumes the count from the point it stopped
and so on until the end of the count or the Reset signal.
In this mode, the front -Start/Stop button (if t.UFt = 2)
acts exactly in the same way as the CNT input with the
addition that, when kept pressed for 2 s during the count-
ing, carries out the Reset command.
If the counting is finished, pressing the key carries
out the Reset-Start command at the same time.

At 1st impulse on the CNT input the timer is reset and
started, at the 2nd impulse, if given before the end of the
count, the count is stopped (disabling the output if active)
and the 3rd impulse starts a new cycle, otherwise, if the
2nd impulse should arrive after the end of the count it
starts directly a new cycle. In this mode, the front

This operating mode is similar to the one of the tradition-
al timers in which counting is enabled when the instru-
ment is powered while the Reset occurs when power
supply is removed. In this operating mode, the front

5.2.4 Timer Out2 Operating mode
The Output 2 operation can be programmed in 10 different
modes with F.o2t parameter:
F.o2t = oF - Out2 Output disabled
F.o2t = 1- Out2 works like Out1
Out2 output operates exactly like Out1 output in order to
have a double output contact.
F.o2t = 2- Out2 output works as an instant contact
(ON during count)
Out2 is activated during the counting phase and remains
active until the Reset command has been received.

5.2.5 Timer internal buzzer operation
The internal buzzer can be programmed using the F.buF
parameter to operate in the following ways:
oF Internal buzzer disabled;
1 Activated at end of S.t1 time for S.t2 period; sounds also
when keys are pressed. If a Reset command is given
(with key or digital input), the buzzer is silenced imme-
diately. This mode is only active for operations that nor-
mally do not involve the usage of the S.t2 time because
S.t2 is used in work-pause operations that would not
have substantially a well determined cycle end;
2 Activated at s.t1 end for s.t2 time; no sound when keys
are pressed;
3 Sounds only when the keys are pressed:
4 Only external buzzer (if configured on Out2 with F.o2t = 5)
with operation at the end of S.t1 time for a period of S.t2.
5.2.6 Timer operation in case of power supply
failure (backup)
F.but parameter establishes the instrument behavior when
power supply returns after a power supply failure during the
current count:
1 Resets the count;
2 Stops the count by storing the value reached (when the
power returns, it therefore waits for a command to restart);
3 Stores the reached value and, when the power returns,
the count restarts from that value if the conditions for
restarting are present (e.g. the instrument was counting
with a bistable command when the power was lost);
4 The count continues if the internal battery is present and
enabled by connecting terminals 15 and 16.
5.3 Operation as a Pulse counter
5.3.1 Counter display operation
LED is used to indicate:
– Count in progress (steady on);
– Count enderd and Reset status (OFF).
In particular, the count is considered in progress at the
first impulse acquired after the Reset.
After Reset the upper display shows 0000 when counting
mode is UP (F.CnC = uP) or the Set point value if the count-
ing mode is DOWN (F.CnC = dn).
The lower display instead shows the Set point value estab-
lished by the C.ddn parameter which can be set as:
0Active counting set point;
1S.C1;
2S.C2;
3S.tr.
The upper display at the end of the count can be flashing if
EndC = 0or steady ON if EndC = 1.
5.3.2 Counter counting commands
At the first impulse received from the CNT input, the coun-
ter enters the counting state, which is signaled by switching
ON the LED .
While the count is in progress it is possible to view and modify
the Set point, but it is not possible to access the parameter
programming.
In this case, to access parameter programming, the count
must be reset using the RST input or the RESET button if
operational (t.UFC = 1).
The count and the output status Reset occurs auto-
matically if the type of operation is F.o1C = 1(Restart) or
F.o1C = 2(Restart-lap) or it can be done manually in any
case through the RST input if suitably configured (i.FrC = 1)
or by means of the RESET key if operative (t.UFC = 1).
Depending on the frequency of the signal supplied to the
CNT input, it is advisable to appropriately set the software
filter with the i.Hcn parameter which allows to select the
maximum acceptable input frequency for counting and thus
avoid unwanted counts (often caused by contact bounces).
In particular, for instruments with voltage signal inputs
(type V inputs) supplied by alternated current it is recom-
mended not to set the parameter i.Hcn >3as the device
could count the pulses deriving from the mains frequency.
Through the i.diC parameter it is possible to multiply the
number of pulses received at the input and then use the
result as the instrument’s count value, of course, both for the
display and for the output operation.
Counting inversion
Using the .FrC = 2parameter it is possible to configure the
RST input to operate as a count inversion command.
With this setting, while the RST signal is active, the count is
inverted and therefore the pulses acquired by the CNT input
are subtracted when counting UP (F.CnC = 1) or added
when counting DOWN (F.CnC = 2).
With this type of operation, however, it is necessary to pay
attention to the counting speed as the RST input intervenes
with a delay of about 15 ms and therefore the count inver-
sion is not instantaneous. For this reason it is recom-
mended to use the count inversion function only when the
input frequency signal is low.

Using a contact that closes earlier than another to which it is

With bidirectional counting applications, however, it is to
be remembered that the count cannot assume negative
values and therefore once the value 0(count UP) or the Set
point value (count DOWN) has been reached, any inversion
count pulse will not be acquired.

5.3.3 Counter Out1 operating mode
The instrument can be programmed using the F.o1C param-
eter to operate in 3different ways:
F.o1C = 1- Automatic cycle counting (Restart)
When the Set point (counting UP) or 0000 (counting
DOWN) is reached Out1 output is activated and remains
activate for the time set in parameter S.tr, the upper
display shows the value reached and the instrument does
not counts any impulse received during S.tr time. Elapsed
the S.tr time, the output is deactivated, the instrument au-
tomatically resets the count, prepares for a new cycle and
then restarts counting the pulses received.

The operation is similar to F.o1C = 1with the difference
that, while counting the S.tr time, the instrument contin-
ues displaying the value reached, keeps the output active
and counts any pulses received. At the end of S.tr time,
therefore, the output will be deactivated and the count will
continue from the value reached during the S.tr time. The
count Reset occurs when the Set point (S.C1) is reached,
while the output is Reset once elapsed the S.tr time.

1 Activated at the end of count for S.tr period; sounds
also when keys are pressed. If a Reset command is
given, the buzzer is silenced immediately;
2 Activated at the end of count for S.tr period; no sound
