1. APPLICATION
The
MODACT MPSED, MPSPED Konstant electric part-turn
(lever)
actuators operating at a constant speed
are used for remote control and automatic regulation of flaps, louvers and valves. They have been specially
designed for industrial plants. The actuators should not be used for other purposes than those specified, without
prior consultation with the manufacturer.
2. OPERATING CONDITIONS, OPERATING POSITION
Operating conditions
The
MODACT MPSED, MPSPED actuators should withstand the effect of operating conditions and external
influences, Classes AC1, AD5, AD7, AE4, AE6, AF2, AG2, AH2, AK2, AL2, AM-2-2, AN2, AP3, BA4, BC3 a BE3
according to ČSN 33 2000-5-51 ed. 3.
When the actuator is installed on a free area it is recommended to fit it with a light shelter against direct impact
of atmospheric effects. The shelter should overlap the actuator contour by at least 10 cm at the height of 20 – 30 cm.
When actuators are to be installed in the working environment with temperature below -10 °C and in the environment
with relative humidity above 80 %, it is always necessary to use an anti-condensation heater fitted to all actuators.
The electric actuators can be installed in areas with non-flammable and non-conductive dust, provided that this
does not adversely influence their function. Here, it is necessary to strictly observe ČSN 34 3205. It is recommended
to remove dust as soon as its layer is about 1 mm thick.
Notes:
A sheltered location is considered a space where atmospheric precipitations are prevented from falling at an angle
of up to 60° from the vertical.
The location of the electric motor should be such that cooling air has free access to the motor and no heated-up
blown-out air is drawn in the motor again. For air inlet, the minimum distance from the wall is 40 mm. Therefore,
the space in which the motor is located should be sufficiently large, clean and ventilated.
Surrounding temperature
Operating temperature for the
MODACT MPSED (MPSED Control) is from -25 °C to +70 °C or from -40 °C to +60 °C.
Operating temperature for the
MODACT MPSPED (MPSPED Control) is from -25 °C to +60 °C or from -40 °C to
+60 °C
(except 52 260).
Relative humidity from 10 to 100 % with condensation.
