5.
Wire Controller or PLC (0-10V or 4-20mA Input) to pin InBK1 or InBK2 as shown figure
6.
Set the Anti-residual with the white screw as shown figure 4 as describe below:
7.
(Optional): Pins ON1, OFF1, ON2, OFF2 are NPN type Input:
-
When ON (1 or 2) is set to Ground => 24V is applied on BK (1 or 2) output
-
When OFF (1 or 2) is set to Ground => 0V with Anti-residual is applied on BK (1 or 2) output
8.
(Optional): To get an Open Loop control use the external interface power supply (10V DC) as shown figure 2 to supply a
potentiometer or others as describe figure 5.
9.
Auxiliary Analog Sensor
(Teachable Span)
In case of use an analog sensor or two, wire them to Pin Ana1 or Ana2 and teach their voltage or current span with starting the
calibration as describe below (for this use the button Cal as shown figure 6).
If no calibration is done, Ana1 or Ana2 are ignored
.
The Analog Input (Ana) compensates the Brake Input signal control
(InBK) between 20-100%.
To Disable Ana1 or Ana2 compensation, please calibrate Ana 1 or 2 without any connection (unplugged).

diameter compensation
a.
Apply the brake at 0V or 4mA on InBK (1 or 2) or activate the Brake-Off (OFF1 or
OFF2)
b.
Check the Brake armature floats away from the Brake magnet with no sticking
c.
If the armature sticks to the magnet, set the Anti-Residual (AntiR1 or AntiR2) as
shown below until the armature is free with no sticking
d.
Reapply the Brake at 10V or 20mA on InBK (1 or 2) or by returning the Brake-Off
(OFF1 or 2) Pin to its normal position and activating the Brake-On input (ON1 or
2)
e.
If Brake releases freely, make no further adjustments as the Anti-Residual is
now set
