General presentation
L. BERNARD
has developed a new electronic
board for a range of
SINGLE PHASE PROD-
UCTS.
Standard features are :
n
Stop on travel limit switches,
Stop on torque limit switches (memorizes
actions of the torque) when applicable,
n
This new board has the possibility to control
actuators with torque switches, both for
On/Off
and
Class III
modulating application, without a
local control.
Remote indications of positions Open and
Closed,
n
Selection to close Clockwise or Counter
clockwise.
n
This board is available in 2 versions : a simple
On/Off commands version, named
MINIGRAL+
, and an analog command
version, named
MINIGAM+
.
It offers the advantage of a compact product
with simplified wiring :
4 wires are sufficient
for basic operating.
The actuator status are shown by
LEDS
on the
electronic board : Green LED for Open com-
mand, Red LED for Close command and
Yellow LED when a torque switch is tripped.
Those boards are designed to equip single
phase actuators (115/230 V - 50Hz/60Hz), with
small motors (power less than 300 W) and are
located inside the main housing of the actua-
tor,
without any additional box.

l
Fault monitoring relay
A fault monitoring relay detects all malfunc-
tions or unavailability and communicates this
information remotely. The relay is normally
energized and reset in case of fault.
Contact rating specification
8 A 250 Vac;8 A 125 Vac;8 A 30 Vdc
l
Supply for a heater
l
Remote position signal, with a poten-
tiometer, for
MINIGRAL+
(always includ-
ed with
MINIGAM+
)
The detected faults are:
n
Power supply failure
Blown fuse
n
Thermal motor protection tripped
n
Torque limit switch tripped

MINIGRAL+
The
MINIGRAL+
is designed for the On/OFF
command of actuators. It can be installed
inside both On/Off and Class III modulating
actuators.
It allows you to command and supply power
with only 4 wires :
n
2 for single phase power
1 for open command
n
1 for close command
n
The On-Off commands are fully isolated with
optocoupler. They are not self-holding, so the
actuator continues to function as long as the
signal is maintained and it stops when
released.

: actuator without torque limit

MINIGAM+
The
MINIGAM+
is designed for the analog
command of actuators. It can be installed
inside Class III modulating actuators.
In combination with a potentiometer,
MINIGAM+
allows an accurate positioning
(<2%), with a settable dead band. The input
signal can be :
n
4-20 mA
standard configuration
0-20 mA
configuration by switch
n
0-10 V
configuration by switch
n
MINIGAM+
offers a position signal that is in
accordance with the input signal. Both signals
are connected to a common potential.
