OPEN GATE INDICATOR LIGHT FUNCTIONS
The open gate indicator light shows the status of the gate by means of a series of signals.
These signals may be summed up as follows:
Light off = gate closed
Slow blinking light = gate opening
Fast blinking light = gate closing
Light with double blink = gate open in pause phase
Light on = gate open in STOP phase
T200 SPECIAL FUNCTIONS
Other functions may be inserted using special procedures when switching on the control unit.
TIMER function for recharging the pressure in the hydraulic motors
The control unit automatically provides power for a few seconds to the motors with an interval of approx. 4
hours to keep the oil pressure inside the hydraulic systems constant.
This function is not normally connected.
To change the setting:
1 - Cut off the power to the control unit.
2 - Press the P/P button (det. 18 of fig.1),
3 - Power the control unit keeping the P/P button pressed for 3 seconds.
The LED L1 (det. 3 of fig. 1) gives a short blink to indicate the transition.
- LED with fixed light = recharging has not been carried out.
- Fast blinking LED = recharging is carried out approx. once every 4 hours.
Whenever this procedure (RESET + P/P pressed for 3 seconds) is repeated, the setting changes.
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:
1 - Cut off the power to the control unit.
2 - Press the P/P and STOP/PROG buttons simultaneously (det. 18 and 19 of fig. 1)
3 - Power the control unit keeping the P/P and STOP/PROG buttons pressed for approx. 3 seconds.
The LED L1 (det. 3 of fig. 1) gives a short blink to indicate the transition.
- 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.
Function of reducing the pause time with photocell 1
When this function is connected, upon passing in front of the photocell 1 (FT1, terminal 22), the pause time
is decreased, whatever its value, to 2 seconds.
This function is not normally connected. To set this function, proceed as follows.
1 - Cut off the power to the control unit.
2 - Press the STOP/PROG button (det. 19 of fig. 1)
3 - Power the control unit keeping the STOP/PROG button pressed for approx. 3 seconds.
