Wait time (0x85)
This parameter is expressed in seconds and can be set with a value from 0 to 250 sec.; the factory setting is 5 sec. This function enables programming on
the Control unit of the required wait time to pass between the end of an Opening manoeuvre and the start of a Closing manoeuvre.
Always close (0x87)
• active (0x86)
This parameter is ON/OFF; the factory setting is "OFF". This function is useful in the event of a power failure, even brief. In fact, during an Opening manoeuvre
if the automation shuts down due to a power failure and the function is active (ON), the Closure manoeuvre is performed normally when the electrical power
is restored. On the contrary, if the function is not active (OFF), the automation remains stationary when the power is restored. Note – For reasons of safety,
when the function is active, the Closure manoeuvre is preceded by a wait time as programmed in the function "pre-flashing time". Note: auto close does not
operate in hold-to-run close mode.
• mode (0x8a)
This parameter is factory set on the mode "always close". The function has 2 operating modes:
❒ standard – For this mode, refer to the function "active" under the item "always close";
❒ save automatic closure - Enabling this mode, you may obtain two results when power is restored after a power failure: a) execution of automatic closure,
observing the time as programmed in the function "pre-flashing time", if the timeout interval of this time was in progress at the time of the power failure;
b) execution of closure manoeuvre if the automatic closure was in progress at the time of the power failure and the manoeuvre had not been completed.
Note – If the automatic closure manoeuvre was cancelled before the power failure (for example, by sending the Halt command), the Closure manoeuvre is
not performed when the power is restored.
Wait time (0x89)
This parameter is expressed in seconds and can be set with a value from 0 to 20 sec.; the factory setting is 5 sec. This function enables programming on the
Control unit of the required wait time to pass between the end of an Opening manoeuvre and the start of a Closing manoeuvre.
Pre-flashing (0x93)
• active (0x94)
This parameter is ON/OFF; the factory setting is "OFF". When this function is set to "ON" it enables the activation of a flashing time, which passes between
activation of the flashing light and the start of an Opening or Closing manoeuvre. This time is adjustable and useful to for an advance indication of a hazardous
situation. Important – When this function is not active (OFF), the flashing light is switched on at the same time as the start of the manoeuvre.
• time in opening (0x95)
This parameter is expressed in seconds and can be set with a value from 0 to 10 sec.; the factory setting is 3 sec. This function programs the flashing time
which indicates the imminent start of an Opening manoeuvre: it is associated with the pre-flashing function.
• time in closing (0x99)
This parameter is expressed in seconds and can be set with a value from 0 to 10 sec.; the factory setting is 3 sec. This function programs the flashing time
which indicates the imminent start of a Closing manoeuvre: it is associated with the pre-flashing function.
Block automation (0x9a)
This parameter is ON/OFF; the factory setting is "OFF". This function enables automation operation to be disabled, by setting the value to "ON". In this case
no type of command is acknowledged or performed, with the exception of "High priority step-step", "Release", "Release and close" and "Release and open".
Block keys (0x9c)
This parameter is ON/OFF; the factory setting is "OFF". This function disables operation of the keys present on the control unit.
Test mode (0xA9)
This parameter automatically sets the behaviour of inputs and outputs when using specific safety devices. The following modes are available at this time:
0: all inputs and outputs use their factory settings or settings made by the installer;
1: operation with photocell barriers with test device.
This mode uses ING1 input (as the photocell input) and the traffic light OUT-TL1 output. When starting a closing manoeuvre, a test is run which activates the
output and checks that the input deactivates. Normal operation is then restored. Important – if the mode is reset to 0, OUT-TL1 returns to its set value, while
ING1 is set to not connected to avoid unintentional commands.
Brake mode (0x36)
This parameter sets the parking brake's operating mode. There are 3 modes:
0: brake disabled (not powered);
1: brake negative. During the manoeuvre, the brake is powered to release it and allow the motor to run. When the manoeuvre is completed,
power to the brake is shut off, thus automatically engaging it.
2: brake positive. During the manoeuvre the brake is not powered and the motor is free to run. When the manoeuvre is completed, the brake
is powered up, thus engaging it.
3: brake negative. For 208V three-phase power
4: brake positive. For 208V three-phase power
The factory setting is mode 1.
Short inversion value (0x31)
This parameter is expressed in seconds and can be set with a value from 0,1 to 5 seconds; the factory setting is 3 seconds. This function enables program-
ming of the brief inversion activated by the control unit as a safety manoeuvre following detection of an obstacle or delivery of a "Stop" command.
