1. APPLICATION
The actuators
MODACT MTNED, MTPED
are used for remote two-position or three-position control of valves
by reciprocating linear motion. The actuators can also be used for other devices for which they are appropriate
due to their performance and parameters. Using in special cases should be discussed with the manufacturer.
2. OPERATING CONDITIONS, OPERATING POSITION
Operating conditions
The MODACT MTNED, MTPED actuators should withstand the effect of operating conditions and external
influences, Classes AC1, AD5, AD7, AE4, AE6, AF2, AG2, AH2, AK2, AL2, AM2-2, AN2, AP3, BA4 and BC3, according
to ČSN Standard 33 2000-5-51 ed. 3.
When installed on a free area the actuator should be fitted with a light shelter against direct action of atmospheric
effects. The shelter should overhang the actuator contour by at least 10 cm at the height of 20 – 30 cm.
Installation of the actuators at a location with incombustible and non-conducting dust is possible only if this has no
adverse effect on their function. At the same time, it is necessary to strictly observe the ČSN Standard 34 3205. It is
advisable to remove dust whenever the layer of dust becomes as thick as about 1 mm.
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.
Temperature
Operating temperatures for MODACT MTNED electric actuators ranges from -25 °C to +70 °C and -40 °C to +60 °C.
Operating temperatures for MODACT MTPED electric actuators ranges from -25 °C to +60 °C and -40 °C to +60 °C.
Classes of external effects
– extract from ČSN 33 2000-5-51 ed 3.
Class
1) AC1
– above-sea level ≤ 2000 m
2) AD5 – spouting water; water may spout in all directions
AD7 – shallow immersion, possible sporadic partial or full coverage (only MTPED)
3) AE4
– slight dust formation
AE6 – strong dust formation (only MTPED)
