1. What is the Duty Cycle? What will happen to the electric putter?
Rated Duty Cycle = continuous operating time/continuous operating time + rest time
Duty Cycle = 10% = [2min/(2min+18min)] **
When the Duty Cycle exceeds 10%, the life of the electric push rod will decrease relatively. When the Duty Cycle is too high, the electric push rod will be damaged at an accelerated rate.
2. What is a Holding Force? Is it related to the selection of electric push rod?
Self-locking force: the force that the weight will not slide down when the electric push rod stops in the moving stroke.
There is a pair of weight directly under the force of the electric push rod (vertical direction), the weight is not under the force of the electric push rod horizontal movement is irrelevant.
3. Can the electric push rod be used when it exceeds the rated load?
No, the electric push rod may not operate and cause the motor to burn out, or premature damage.
4. Can two or more electric push rods be synchronized at the same time?
Standard product can not, only can be synchronized, because the speed of the motor (RPM) is not enough *, more or less some error.
But the electric push rod with position feedback can be used to achieve the function of synchronization.
5. Can controller drive two electric push rods at the same time?
Yes, but the wiring of the controller or manual switch must be modified and the load of the two electric push rods must be halved.
6. Can the controller and the putter be universal?
Yes, and the company's products can match
7. The polarity input of the wire (+)(-) is wrong, will it affect the electric push rod?
Yes, because FIRST electric putter is used DC motor may have the following effects.
A. The extension and retraction direction of the electric push rod is wrong.
B. If the magnetic reed switch is installed, the magnetic reed switch will fail or cause damage to the electric push rod structure
8. How to control the stroke of the electric push rod?
There are three control modes :(1) internal limit switch (2) external limit switch (3) overcurrent control
9. What kind of limit switch is used for the electric putter of FIRST?
FRT series electric push rod uses built-in micro - switch. (default Setting: Close) External limit switches can also be configured
10. Can the electric putter be used if it is not equipped with limit switch?
Yes, but it must be controlled by the over-current setting of the controller.
11. Can the stroke of the electric push rod be adjusted arbitrarily?
Can not be
12. Is the high speed electric push rod (30 mm/ SEC) available?
Yes, L fast series is optional. But the force is going to be smaller.
13. Can the electric push rod with Load over 7000N be provided?
14. Is the electric push rod with synchronous and positioning functions provided?
Yes, choose our putter rod with sensor
15. Does the FRT electric push rod motor have overheating protection?
Can be installed according to customer demand (motor surface temperature 70oC) automatically cut off the motor power supply, the temperature drops below 70oC automatically resume operation)
16. Can the electric push rod be provided when the stroke exceeds the size on the catalogue?
Yes, but we have to consider the Load and the strength of the electric putter.
17. Can you supply the controller with battery?
Yes, it is optional.
18. What is the ambient operating temperature of the FRT electric push rod?
-5℃ ~ 5℃
19. Why does FIRST's electric push rod not have UL roll label?
Because the FRT's electric push rod uses DC motors of less than 24V, normally DC motors of less than 24V do not require UL certification.
