resolved and all alarms have been reset at the control panel. The alarm triggered by the
diagnostic program for electronics is automatically reset, when the problem is solved.
4 SETTINGS
4.1 General
Channel-specific settings can be divided into two groups
•Set values
•Configuration settings
Set values are lubrication system basic values, for example lubrication cycle and maximum
pressurization time. Set values can be changed in settings mode.
Configuration settings determine the channel functions according to the lubrication system.
These settings are usually factory settings and there should not be any reasons to change
them during operation.
All settings are password-protected. Different passwords are used for set values and
