Jaw 1 → monitoring open jaw position
• Move base jaws to OPEN position.
• Screw the set-screw (61) into the bore hole o up to the stop and
then unscrew it again by a few turns.
• Slowly screw the set-screw (61) into the bore hole oo until the
differential pressure sensor emits a switching signal.
• Hand-tighten set-screw (61) in bore hole o.
• Screw set-screw (63) in both bore holes and hand-tighten.
Jaw 2 → monitoring closed jaw position
• Move base jaws to CLOSED position.
• Screw the set-screw (61) into the bore hole oo up to the stop
and then unscrew it again by a few turns.
• Slowly screw the set-screw (61) into the bore hole o until the
differential pressure sensor emits a switching signal.
• Hand-tighten set-screw (61) in bore hole oo.
• Screw set-screw (63) in both bore holes and hand-tighten.
7.4.3 Leak test
The following components are required to check for leaks:
pressure gauge, shut-off valve, supply line and quick coupler.
• Check for leaks in the clamping system in the OPEN and CLOSED
positions.
1. Connect the components to the open CLOSED connection in the
following order:
pressure gauge – shut-off valve – quick coupler – supply line.
2. Pressurize the clamping force block.
3. Close the shut-off valve and remove the supply line.
4. Let the clamping force block sit clamped for 24 hours.
5. After 24 hours, the clamping force block is:
– sealed if the pressure gauge indicates a drop in pressure of
less than 0.5 bar.
– leaking if the pressure gauge indicates a drop in pressure of
more than 0.5 bar.
If the clamping system is leaking, check the screws first (e.g., with
Metaflux leak detection spray). Seal any leaking screws.
Once the fittings are sealed, check for leaks and replace if
necessary (see Disassembling and Assembling the Clamping Force
Block ).
