ADJUSTMENT (BMS) (continued)
RELEASING BY MIN. ONLY (CONTINUED)
Then in the following conditions:
- set-point spring decompressed (adjustment screw (5)
unscrewed),
- pressure equal to releasing pressure required in the BMS,
adjust the min. hook (2) to Y = 1.5 mm (detection stage set).
Jam nut (6).
Adjusting min. only releasing pressure
Same procedure as paragraph "Adjusting max. only releasing
pressure".
RELEASING BY MAX. AND MIN.
Adjusting the push button
The min. hook (2) is completely unscrewed.
Then in the following conditions:
- set-point spring decompressed (adjustment screw (5) unscrewed),
- pressure equal to the max. releasing pressure required in
the BMS.
adjust the push button (1) to X = 0 mm (detection stage set).
Release manually.
Unscrew the push button (1) 2 turns, which represents a
distance of approximately 1.5 mm.
Jam nut (3).
Adjusting the releasing pressure to max. and min.
Max. adjustment
Same procedure as paragraph "Adjusting the max. only
releasing pressure".
Min. adjustment
Admit an average pressure between max. and min., (for
example regulator set-point pressure).
Set the detection stage.
Admit a pressure equal to the min. releasing pressure required.
Screw the hook (2) progressively until detection stage release.
Jam nut (6).
Check the pressure value at the releasing point (adjust if
necessary).
MAINTENANCE
(BMS)
Control
Æ Slam shut releasing (twice yearly)
Æ External tight shut
Æ Impulse part (diaphragm, bellows or piston)
Disassembly
Æ Unscrew the connector form the sensing line
Æ Remove the safety manometric box (BMS)
Æ Unscrew the blocking nut on the adjustment screw (manually)
Æ Unscrew the adjustment screw (resetting tool)
Æ Remove the hook or plate, depending on the type of
BMS 1 or 2, from the detection rod (flat spanner 7)
Æ Remove the upper case
BMS 162 (flat spanner 11)
BMS 071 (flat spanner 8)
BMS piston 27/17 (key 5)
BMS bellows 236/315 (key 5)
Æ Disassemble the set plate/counter plate
(Flat spanner 17 and pliers)
or
Æ Remove the bellows or piston and guide (manually)
Assembly
Æ Proceed in reverse order to disassembly
BMS torque values
Æ Upper spring case/manometric box
BMS 162: 8 N.m
BMS 071: 5 N.m
BMS piston 27/17: 6 N.m
BMS bellows 236/315: 6 N.m
Æ BMS 162 and 071 nut/diaphragm plate: 20 N.m
