Plug-In Assembly Configuration 551Once POWER ON SRQ is enabled, a low power condition in either the 3497A ORthe 3498A will cause an interrupt and there is no way to tell if the interrupt resultedfrom power loss in the 3497A, 3498A or both. If the 3497A is not set for POWERON SRQ, interrupt is NOT sent to the controller, even if either or both instrumentsexperienced a power failure. Also, note that POWER ON SRQ occurs when poweris regained, NOT when it is lost.To enable the 3497A for POWER ON SRQ, it is necessary to set the POWER ONSRQ switch (position #7) on the 3497A Outguard Controller to the "1" position.To do this, see Figure 181 and use the following sequence.First verify that all power is removed from the 3497A and 3498As connected. Then,remove the safety cover, loosen the retaining screws holding the outguard controllerand remove the outguard controller. Locate the 7-position DIP switch and set switchposition #7 to the "1" position (see Figure 1811.Replace the outguard controllerand the safety cover.0 0 0 1 1 ADDRESS SELECT0 0 1 0 00 1 0 1 10 1 1 0 00 1 1 0 10 1 1 1 00 1 1 1 11 0 0 0 01 0 0 0 11 0 0 1 01 0 0 1 11 0 1 0 01 0 1 0 11 0 1 1 01 0 1 1 11 1 0 0 01 1 0 0 11 1 0 1 01 1 0 1 11 1 1 0 01 1 1 0 11 1 1 1 0OUTGUARO CONTROLLERFigure 181.
