CUSTOMISED PARAMETER PASSCODE PROTECTION
COUNTING OPERATION MODES
Page 5
= 1 Bistable Start/Stop
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.
RESET PARAMETERS TO DEFAULT VALUE
KEY LOCK FUNCTION
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.
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.
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.

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.

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
).
