• PDC-A: F7 is tripped using S1. To apply power to the PHS for service movement, resetF7 and wait two minutes for the table firmware to initialize.

Fig. 6: F7 in PDC-APos. 1 F7

Relay K7 uses normally closed contacts. When the system is powered OFF in thenormal way, the firmware energizes K7 to remove power. Only when S1 is used

will the relay de-energize to allow power from F7 to flow to the table for testing.

NOTE With software versions VA40 and higher, the PHS controlsrun on the UMAS.

Therefore, the UMAS has to be switched on with breaker F11in addition to F7.

• In normal operation when using the gantry controls, the software lim-its the vertical movement to 10 mm before the mechanical limit; how-ever, this position is referenced to the floor and can be affected byshimming. Therefore, the microswitches are adjusted to operate 5

mm before the mechanical limit. Using the service movementswitches will allow the table to raise or lower until the microswitchoperates.

• Turn on F7 and raise the table using the Service controls (Servicemovement of PHS / p. 21) to a position just before the mechanicallimit.

Do not drive to the mechanical limit.

• Turn off F7.

• Use a 6 mm hex key in the manual lift screw (Manual vertical move-ment of tabletop / p. 22) and move the table to the mechanical limit.Measure the table height from the floor and note down this measure-ment.

Storage of table T3C PHS - LMAS

NOTE PHS relevant parameters are stored in the configuration tableT3C. Table T3C is stored on the PHS-LMAS board - Source:Volatile. If the LMAS board is replaced the original T3C has to

be restored on the new LMAS; otherwise, the PHS may notfunction correctly.

There are two ways to save the original T3C table

1. Prior to removing the old LMAS board, perform function“Service > Control > table load/modify”. Select table T3C,set radio button “Volatile” and press <Go> to display thetable. Select radio button “Persistent” and press <Go> toback it up on the UMAS board.

2. The original T3C is already stored on the UMAS becausethis step is performed automatically with every PHS

adjustment (vertical or horizontal). You may check if aPHS adjustment was performed in the past.

Restoring the T3C table on the new LMAS board:

Use function “Service > Control > table load/modify”. Selecttable T3C, set radio button “Persistent” and press <GO> todisplay the table stored at the UMAS. Select radio button“Volatile” and press <Go> to download it onto the LMAS.

• Select Local_Service > TuneUp.

• Select FRU Replace.

• Select PHS - LMAS.

• Press <Go> to start the tour.

- Save table T3C prior to replacing the part and restore table T3C after replacement asdescribed in the above note.
