2.3 SAFETY DEVICES AND SIGNALLING PLATES
CAUTION
Before commissioning and operating the ROTOMEC hydromechanics coupling, make sure
that signal- ling plates and all safety and temperature control devices are correctly installed, used
and are efficient; if not, restore good working conditions before going on with installation and use.

DESCRIPTION
A
SLINGING DEVICES FOR LIFTING:
They enable lifting through grip and slinging points and safe handling of the
hydromechanic coupling.
B
DM ASSEMBLY DEVICE:
It enables the safe fitting of the hydromechanic coupling fitting on the drive end shaft.
C
DISASSEMBLY DEVICE “VE” or “SE”:
It enables the safe, removal of the hydromechanic coupling from the driving
shaft.
D
DEVICES FOR COUPLING CLAMPING ON “TT” DRIVE SHAFT:
They enable to safely fix the hydromechanic
coupling
E
1
FUSIBLE PLUG “TF”:
FUSIBLE PLUG “TF”:
It detects any leakage of transmission fluid from the hydromechanic coupling and any drive
failure at the driven machine, when the maximum temperature of the fitted TF is exceeded.
E
2
EXPANDABLE TRIP PLUG “TE”:
EXPANDABLE TRIP PLUG “TE”:
It permits to detect the overheating value as set up in the fitted TE through release
of the signalling stud by a suitable microswitch, which shall be of “ET” type for standard and “ETA” type for ATEX
manufacture.
E
3
PLUG WITH thermocouple AND RPM CONTROLLER “PM” with “T09”:
PLUG WITH thermocouple AND RPM CONTROLLER “PM” with “T09”:
It permits to detect the maximum
temperature of the fitted PM plug and to transmit an electromagnetic pulse signal, which is detected by suitable
sensor and sent to the electronic control unit, which in turn compares the rpm with the threshold setpoint.
E
4
DEVICE FOR OVERLOAD CONTROL “SCD”:
It detects the output rotation speed of the coupling. This SCD device
is composed of an rpm controller, which receives a pulse train through a sensor and generates a signal for alerting
and stopping the system in case of extreme speed reduction.
