Installing Entrapment Protection Devices
(requires Terminal Blocks P/N TBT2A-5)
Devices such as Infrared (IR) Beams and Safety Bump Edges allow safe automatic or latch closing of the door and can be wired
directly into the MCB via an appropriate cable entry. Grifco® Entrapment Protection Devices such as the Protector System and
Bump Edge are wired into the quick connect inputs located next to the door behaviour dip switches on the MCB.
VDC OUT:
Accessory power 24Vdc - unregulated
(max 150mA)
IR1:
Monitored Grifco® Protector System, or
NC (normally closed) switching input
IR2:
Monitored Grifco® Protector System, or
NC (normally closed) switching input
For more detailed information on installation refer to the Grifco
®
Protector System manual.
BUMP:
Monitored 8K2 Resistor type Bump Edge input.
Erase Entrapment Protection Devices
Press RST button on the MCB for at least 10 seconds until green LED blinks rapidly.
Reactivate Entrapment Protection Devices
Follow the above install instructions.
Note: When installing Entrapment Protection Devices ensure that the door is at the open limit position.
Note: All Entrapment Protection Devices need to be activated once after installation to be learned correctly. Normally closed
Entrapment Protection Devices and monitored Bump Edges require one simulated obstruction to be learned by the opener.
Once learned, latch closing will be allowed when set.
Note: The eDrive +2.0 features “constant pressure to close”. This means that if an Entrapment Protection Device fails, the
opener can still ‘inch down’ (unless an expansion board is used).
Additional switchgear (eg. dedicated open/close and Auto Mode etc)
Caution!
Any access control intended for these terminals must
be user operated and in line of sight with the door.
The
2.0
can be easily interfaced by the reverse side of
the controller push button panel (Refer to adjacent diagram).
To do so you will need terminal blocks (P/N TB210) available
from your local commercial door dealer or Chamberlain®.
Note: A controller must always be plugged in (see page 17 no.
2) for the opener to function. When utilising the AUTO or
ESTP terminals the respective bridge must be removed, refer
right.
Note: Additional 24VDC devices must not draw current from
the MCB in excess of 150mA. Excessive load from connected
devices will cause malfunction of the 2.0 opener. For
additional loads, use a separately mounted power supply.
Toggle Input (2 wire)
A 2 wire toggle input is provided on the MCB (see page 17) to allow single button (or access control) operation.
The input will operate as “open-stop-close-stop-etc.”
If Auto close is set, the toggle behaviour will become “open only”.
When the toggle input is bridged* and held (eg. a timer or latching switch) the door will remain open (ie Auto Close ignored). If
the bridge is released, Auto Close will resume.
* If an EB is fitted, this feature will not be available on the MCB toggle input. Use EB com open
input instead.
CAUTION: Grifco
®
Protector System
must not be connected to VDC out.
