SETTING THE SLOWDOWN RAMP
The control unit is normally set to carry out optimal deceleration ramps for piston type motors, where the slowdown function
is used.
Should there be any jerking of the gate when passing from normal to slowdown speed or the passage is abrupt, this
deceleration ramp may be changed as follows:
- Cut off the power to the control unit.
- Power the control unit keeping the P/P and STOP/PROG buttons pressed for approx. 3 seconds.
- slow blink = ramp value for SLIDING
- fast blink = ramp value for PISTON.
Whenever this procedure (RESET + P/P and STOP/PROG pressed for 3 seconds) is repeated, the setting changes.
PARTIAL TIME STORAGE CUT-OUT
This version of T200 offers the possibility of cutting out partial time storage. This function is useful when the
motor has a built-in mechanical or hydraulic slowdown system (e.g. BLUES 21)
To remove partial time storage, proceed as follows:
1 - Cut off the power supply to the control unit.
2 - Press the button P/P (part 20, Fig. 1)
3 - Power the control unit again keeping the button P/P pressed.
4 - Within 3 seconds press the STOP/PROG button as well.
5 - LED L1 (part 8, Fig. 1) blinks quickly indicating that programming has been successful.
To return to the original setting on the control unit, that is, with partial time storage active, repeat the pro
cedure from point 1 to point 4. LED L1 blinks slowly indicating the successful transition.
CAUTION!
Upon cutting out the partial time storage also the control unit electronic slowdown function is auto
matically cut out (function dipswitch No.9). It will also be impossible to use the anti-crushing board MAS200.
PARALLELING 2 MOTORS
With overhead door installations using two motors or in any other type of installation where the motors must move together
to M2.
The only active limit switches are those connected to terminals 20 and 21.
To program working and pause times, see types 3 and 4.
