6.6 The [Weekly timer] setting dialog.
In this dialog, you can determine the timeframe for the machine to be ready for op-
eration. For example, the solder in the pot will be heated from the standby temper-
ature to the set temperature in due time, so that the solder has reached its set
temperature when production is started. The modules switch-on time and the time
ahead of it can be defined in the setting dialogs of the units.
ü Opening a dialog:
a) click on the
button in the top toolbar of the start dialog.
ð If the [Password:] input field is displayed:
b) enter user name and correct password.
NOTE
Are any changes possible?
The [Weekly timer] user rights are required to access this dialog. Without name and
password, the settings can only be displayed. In this case, press the [ESC] key on your
keyboard, or click on the [Cancel] button when a password is required.
After entering [User name] and [Password:] correctly, the [Weekly timer] setting
dialog is displayed:

6.6.3 Setting the switch-on and switch-off times
Switch-on time and operational readiness
The switch-on time set in the weekly timer defines the timing of the machine oper-
ational readiness.
The weekly timer automatically calculates when the modules must be turned on.
For this calculation, the data in the corresponding setting dialogs is taken into ac-
count.
An example: In the [Soldering module] input dialog, a pre-heat time can be entered
into the [Solder pot]. If you enter a preheating time of 100 minutes for the pot, the
weekly timer enables the pot heating 100 minutes before the defined switch-on
time. The machine is then ready for operation at the set time, and is in the operat-
ing mode [Maintenance mode].
NOTE
The infeed remains blocked!
The infeed is not released automatically; it remains blocked.
Switch-off time and production end
The switch-off time set in the weekly timer defines the timing of the machine "pro-
duction end". The timer is then in the OFF phase. When the switch-off time has
been reached, the following steps are performed in sequence:
– The machine infeed is blocked.
– The board which is still inside the machine is completely processed and con-
veyed out of the system.
– All heaters and preheaters are switched off.
– The solder temperature is kept at standby temperature.
– The release is blocked.
– The conveyors are switched off.
You can set up to 20 switch-on and switch-off times. The registers to set the switch-
ing times are located in the right section of the dialog:
– [On day]: here, you can select the weekday when the system will be ready for
operation.
– [On time]: Here, for the [On day], you can set the [On time] when the system
shall be ready for operation.
– [Off day]: here, you can select the weekday when the system will be disabled.
– [Off time]: Here, for the [Off day], you can enter the [Off time].
– [Active]: By clicking on the button repeatedly, the following symbols are dis-
played in sequence:
The switching process is enabled and being performed.
The switching process is disabled. It remains visible in the list, but it is not per-
formed.
