Type
Wattmeter relay
INPUTS
The wires carrying the SLOW and FAST current, must
enter through the suitable holes of W 17, marked by S/L
(SLOW), F/V (FAST). No fixed direction is required in
making the wires pass through the holes.
The 3 phases are connected to the pins 28-26-24 (Input
R=800kohm).
The maximum three phase voltage is 415 Vac. For higher
voltages the Drop Resistance M 08: must be applied (See
accessories) (Ref. Fig. 10 and TAB. A).
For motor voltage values outside 400V, the reference
values of In and In tick marks showed in TAB 1 have to be
reconsidered, (see remark 3).
ANALOG OUTPUT
On the pins 31-30 (+ on 31) it is available a voltage 0÷10V
(1mA max) proportional to the active absorbed power, and
consequently proportional to the hoisted weight. The volts
of the analog output correspond to a different value of kW,
according to the range of the current (see Tab. 3).
The analog output can be displayed during the setting
operation or the crane working in order to give to the
operator information regarding the size of the hoisted
weight.
Il can be used with a DC Voltage relay (VD 04 or E 411)
for a pre-alarm or with an DVD 08 for a permanent display.
OUTPUTS: (3A - 230 Vac resistive load)
RA relay: pin 16-17 NO (normally ON) all the alarm
conditions make it change in OFF condition; it is used to
stop hoisting.
RB relay: pin 13-14 NO (it closes for changing to FAST).
If in SLOW operation (during TR), no ALARM condition
has taken place, it allows change over FAST speed.
(Fig.3).
REMARK 7
It is warmly suggested the application of SNUBBER "RC"
on the contactor coils (it is preferable to use those
recommended by the contactor manufacturer).
REMARK 8
Do not leave floating wires connected to pins 8, 9, 30, 31.
SUPPLY
2VA 50-60 Hz ±10%
PIN 20-22: 230 VAC or 115 VAC or 48 VAC or 24 VAC
INSULATION: galvanic separation it is given by the supply
transformer.
SIZE: 100x75x110 mm per DIN
Accessories (on request):
E 405 A: Transparent protection, fitted for lead closure,
M 08: Drop resistances for V > 415V.
WORKING TEMPERATURE: -10°C÷+60°C
WEIGHT: 0,500 Kg - COLOUR: grey.
FUNCTION
It monitors the active power absorbed by a 2 pole motor
(or 2 speeds motor), or two motors with one speed, or one
motor with one speed.
USE
Applied for monitoring and limiting the hoisted load, in
place of LOAD CELLS
