SET TIME PROGRAMMING (FAST MODE)
1. To set the delay times (set times) press the key, the SET LED will illuminate and the display will show (parameter acronym) and its
programmed value. To change the value press the key to increase the value shown or the key to decrease it. Note: Press the keys for
longer than 1 second to increase/decrease the numerical value more quickly.
Through programming the parameter it is possible to select which set times can be set in this fast mode. An option also exists which allows the
setting of the set time value only using the keys without pressing the key in advance ( = 8). The options for the parameter
are as follows:
oF No set time can be set with the short key (if pressed and released the key has no effect).
1 Only set time value can be set with this procedure.
2 Only set time value can be set with this procedure.
3 and set time values can be set with this procedure.
4 Only set time value can be set with this procedure.
5 and set time values can be set with this procedure.
6 and set time values can be set with this procedure.
7 , and set time values can be set with this procedure.
8 set time value can be set directly with the keys.
For example, when the parameter is set to 1 or 3, the procedure is as follows:
- Press and release the key, the display shows alternated with the value.
- To change the set time, press the key to increase the value or the key to decrease the value.
- If = 1, once the desired value has been set, press the key to exit the set time programming mode.
- If = 3, pressing and releasing the key the display shows alternating with the value. To change the value use the keys using the
same method as for the value.
- Once the set time(s) have been programmed, press the key to exit the set time programming mode. If no key is pressed for over 10 seconds the
display will automatically return to normal operation.
x and can be set within the limits established by parameters and and can be set within the limits estblished by and
. .
PARAMETER SETTING MODE
To access the timer function parameters when passcode protection is disabled, press the key for 5 seconds, after which the display shows the code
that identifies the first programmable parameter. Use the keys to select the desired parameter then press the key, the display will then show
the parameter code, alternated with its value, that can then be changed with the keys. Once the desired value has been reached, press the
key again to store the new value, the display will then return to show the parameter code. Press the keys to select any other desired parameters
and change them using the same method. To exit the programming mode, press no key for 30 seconds or keep the key pressed for 2 seconds. The
timer display will then return to showing the timing count value.
PARAMETER PROTECTION USING A PASSCODE
The timer has a parameter protection function using a passcode that can be personalised through the parameter. To protect the parameters, set the
x parameter to your desired passcode number.
When the passcode protection is active, press the key for 5 seconds after which the display shows . Press the key and the display will show .
Using the keys, enter the programmed passcode number and press the key again. If the passcode is correct the timer will display the code of
the first programmable parameter and it is possible to program the timer as previously described.
The passcode protection can be disabled by setting = oF.

(PROGRAM MODE)
Notes:
1. All parameters are configured by default as protected so that by simply setting the parameter they are all protected by the passcode.
2. If the passcode is lost, switch the timer OFF then ON, pushing the key during initial test and keeping it pressed for 5 seconds. All programmable
parameters are then accessible and parameter can be set as required.

CUSTOMISED PARAMETER PASSCODE PROTECTION
All parameters are configured by default as protected. To make certain parameters programmable without protection whilst keeping the protection on
other parameters, the procedure is as follows:
- Enter program mode using the passcode and with the keys, select the parameter that must be accessible without passcode protection.
- Once the parameter is selected, if the SET LED flashes the parameter is programmable only after entering the passcode (protected).
If the SET LED is steadily ON the parameter is programmable without entering the passcode (unprotected).
- To change the parameter protection, press the key and keeping it pressed, also press the key.
- The SET LED changes its state indicating the new level of parameter protection (ON = unprotected, Flashing = passcode protected).
If some parameters are set as unprotected, when accessing the programming mode the display first shows the unprotected parameters then the
parameter through which it will then be possible to access the protected parameters.

RESET PARAMETERS TO DEFAULT VALUE
To reset all parameters to the factory default values enter at the passcode request. The passcode must first be enabled by setting parameter
so that the setting is requested. Enter the value and press the key to confirm. The display shows for 2 seconds and then all
parameters have been reset to the factory default values.
KEY LOCK FUNCTION
It is possible to completely lock the timer keys. This function is useful when the timer is being used in an accessible area and unauthorised changes must
be avoided. To activate the key lock, program the parameter to a value different from oF. The value is the time in seconds of key inactivity after
which the keys are automatically locked. When the keys are locked, if any of the keys are pressed the display shows to indicate the key lock is active.
To unlock the keys press the key and key together for 5 seconds, will then appear on the display and all the key functions will be active again.
INTERNAL BUZZER OPERATION
The internal buzzer can be programmed using the parameter to operate as follows:
oF Internal buzzer disabled.
1 The internal buzzer operates at the end of for period. The buzzer also sounds when keys are pressed. If a Reset command is activated (by
a key or digital input), the buzzer is silenced immediately. This buzzer mode is only active for timing operating modes that do not use the time.
2 The internal buzzer operates at the end of for period. The buzzer does not sound when keys are pressed.
3 The buzzer only sounds when keys are pressed.
4 Only the external buzzer output is activated at the end of for period (if OUT2 configured with = 5).

Activating the CNT input starts the timer counting and the CNT input can then be
deactivated. Activating the CNT input again stops the counting on the value reached
(without disabling the output if this was activated). 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 Start/Stop key (if = 2) acts exactly the same way as the CNT
input with the addition that, when pressed for 2 seconds during the counting, performs the
Reset command. If the counting has finished, pressing the key performs the
Reset-Start command at the same time.
= 2 Bistable Reset-Start/Stop
Activating the CNT input resets and starts the timer counting and the CNT input can then
be deactivated. Activating the CNT input again, if done before the end of the count, stops
the count (disabling the output if this was activated). The next CNT impulse starts a new
count cycle or if the second CNT impulse arrives after the end of the count, a new count
cycle is started. In this mode the Start/Stop key (if = 2) acts exactly the same
way as the CNT input.

Activating the CNT input and keeping it active, resets and starts the timer counting and the
count then stops on the value reached when the CNT input is deactivated (disabling the
output if this was activated). This count operation mode is similar to a traditional timer in
which the counting is enabled when the timer is powered and the Reset occurs when the
power supply is removed. In this mode the Start/Stop key (if is different to oF)
only acts as a Reset.
= 5 Bistable Reset-Start/Stop
Activating the CNT input Resets the timer. Activating the CNT input again starts the timer
counting and activating the CNT input for a third time stops the count on the value reached
(disabling the output if this was activated). In this mode the Start/Stop key (if =
2) acts exactly the same way as the CNT input.

Activating the CNT input starts the timer counting and the CNT input can then be
deactivated. Activating the CNT input again, if done before the end of the count, stops
the count (disabling the output if this was activated) and Resets the count. If the second
CNT impulse arrives after the end of the count, a new count cycle is started. In this mode
the Start/Stop key (if = 2) at the end of time acts exactly the same way as
the CNT input.

OPERATION WITH A POWER SUPPLY INTERRUPTION
When the power supply to the timer is restored after an interruption the timing count can be programmed using the parameter to operate as follows:
1 The timing count resets.
2 The timing count stops at the value reached when the power supply ceased. The timing count continues once a new Start signal is activated.
3 The timing count stops at the value reached when the power supply ceased. When the power supply is restored the count restarts from that value if
the conditions for restarting are present (e.g. the timer was counting within a bistable mode when the power supply ceased).
