Page 7: Unit Operation Modes
L-PAK 150/250 Advanced Unit operation modes L-PAK 150/250 Advanced has the following four operation modes: Off mode Standby mode Running mode Idling mode See Section 5.1. Status messages for more information about each mode. How the unit moves from one operation mode to another is explained below. See also Figure 1 for a flow chart showing how the unit goes through its four different operation modes. When the unit is in Off mode, the unit can be put into Standby mode (the unit is ready) with its motor off and the Filter Cleaning Valve (FCV) closed by pressing the Standby/Running button. While the unit is in Standby mode, the unit can be put back into Off mode again by pressing the Standby/Running button. NOTE! If power is lost to the unit, for example if there is a power outage, and Zero voltage detection is set to OFF see page 16, the unit goes immediately back into Standby mode once power is resumed without having to push the Standby/Running button. The unit goes from Standby mode into Running mode when it receives a pilot signal by a valve being opened at one or more work stations (in other words, someone starts to work). The unit’s motor is now on and the FCV is closed. The DIR_Time and SSR_Time timers are not started, see Sections 6.2.4. DIR_Time and 6.2.5. SSR_Time. The unit stays in Running mode as long as there is an active pilot signal. However, the unit can still be put into Off mode by pressing the Standby/ Running button. Note that if only one workstation is connected to the unit, or if only one work station is in use and work stops at that one station, the pilot signal stops. If there is more than one work station connected to the unit, and more than one work station is in use, the pilot signal only stops if work stops at all workstations (in other words, all valves close). -

The settings can be changed to accommodate a suitable time schedule. NOTE! When the timer stops the unit and a valve at a workstation is in its open position, the unit will start immediately once the timer puts the unit in standby mode. It is not necessary to use the timer function. The function can be switched off by setting the display to show only dashes. However, it is recommended that the timer function is used, as this ensures that the unit is switched off even when a valve remains open, for example, over night. NOTE! If the weekly timer has been activated, the amount of time the unit can be used during the day before it automatically goes into Off mode can be extended if the optional external standby button accessory is used, see Section Section 6.3.1.
