3.2 General.
The Protection Devices Thermo Ramsey, series PRO-LINE are made with a
metallic enclosure in aluminium, common for the three models, containing the
microswitches operated through cams by an external lever.
The units may operated from any direction as the microswitches are operated both for
clockwise or countclockwise rotation of the external lever.
For electrical connection are provided N°3 cable inputs.
The cover of the housing is locked by four stainless steel shake-proof screws. Internal
spring are made with corrosion resistant material.
The enclosure is painted in RAL 1018 yellow color, while the external lever is painted in
RAL3020 red colour.
3.3 Belt Run-Off Switch Mod. 60-30G.
It ' consists of a external lever equipped with a roller which, on normal operating condition,
is not in contact with the belt and thus keeps its vertical position.
When the belt runs-off, it touches the roller, tilts it and thus operates the inside
microswitches.
Fig. 3-3-1
The position of the external lever on the shaft may be changed as required, thus allowing
the mounting of the housing on an horizontal, vertical or any inclined plate, but never
inverted.
The roller is sized for a maximum speed of 4000 R.P.M. equivalent to approximately
8 m/sec belt speed.
It contains one alarm microswitch that is activated when the external lever inclination is
15°+/- 2°, and one shut-down microswitch that is activated when the external lever
inclination is 30°+/- 2° on both side. The max lever inclination is ~65°. Each microswitch is
provide of: N°1 (NC) contact + N°1 (NO) contact.
The unit is equipped with a terminal strip for microswitches electrical wiring and with a by-
pass lever which by-passes the shut-down contact to allow the restarting of the belt.
9 / 30 Cod.: PL-000603X-D002G

3.4 Rope Emergency Switch Mod. 60-31G.
It ' consists of a external lever equipped with two pins to connect steel cords for remote
operation of the switch from both sides.
Fig. 3-4-1
When steel cords (on both sides) is pulled, the lever has a mechanical lock, manually
resettable, by the external reset lever. This feature makes remote restarting impossible,
thus eliminating the possibility of restarting the belt when people are locally working on
the conveyor.
The unit is equipped with N°2 microswitches operate at a 18° +/- 2° inclination of
the external lever.
Each microswitch is provide of: N°1 (NC) contact + N°1 (NO) contact.
This devices is used for the safety of the operators on belt conveyors.
3.5 Limit Switch Mod. 60-32G.
It ' consists of a external lever equipped with one contact wheel to be operate by
the controlled machine.
Fig. 3-5-1
The position of external lever on the shaft may be changed as required, thus allowing
the mounting of the housing on an horizontal, vertical or any inclined plate.
The unit is equipped with N°2 microswitches operate at a 18° +/- 2° inclination of
the external lever.
Each microswitch is provide of: N°1 (NC) contact + N°1 (NO) contact.
