Loop Detector; Jumper Settings - Chamberlain HC500ML-24 Installation

LOOP DETECTOR (OPTIONAL)
Jumper OPEN/PED must be plugged
Loop detectors react to metal and the most common use is for cars
or trucks but not for bikes or pedestrians.
Exit loop / Gate Opening Loop
An exit loop is behind the gate and opens the gate when closed,
keeps it open or re-opens the gate.
The jumpers OPEN/PED must be PLUGGED (in place).
The gate requires installed photocells and timer to close activated.
In addition, the feature "Fast closing" can be activated.
Refer to section "Description of Push Buttons P1, P2 & P3"

JUMPER SETTINGS

RADIO
The radio jumper is required to program remote controls.
For programming procedure please refer to the respective section in
this manual.
FREE: No programming of remote controls possible
PLUGGED: Programming of remote controls possible
Important: Keep jumper "RADIO" free (disconnected)
if not in use!
STOP/8,2 KOhm
Defines whether the terminal STOP/8,2KOhm is used in emergency
stop mode or safety edge mode. With an emergency stop any
movement of the gate will be stopped. When used for a safety edge
the gate reverses for aproximately 20 cm.
FREE: Factory setting is 8,2KOhm. Safety edge or
8.2kOhm resistor is required.
PLUGGED: Emergency stop required. In this case the
resistor must be removed and replaced by the
switch or a switch circuit.
OPEN/PED
Defines if a key switch opens the gate completely or partially.
Note: If the jumper OPEN/PED is plugged and timer to close is
activated as well, the functionality of the terminals "key symbol" and
"COM" changes. See section "Loop Detector" above.
FREE: opens partially (ca. 100 -150 cm)
PLUGGED: opens completely
PHO 2 MODE
Defines whether the second photocell is active in closing or in closing
& opening.
FREE: active in closing
PLUGGED: active in closing and opening
FIXED WIRE JUMPER:
OBSTACLE
Factory-equipped with fixed wire jumper. Cutting through increases the
operating power at the control.
CAUTION: If the jumper is severed, the door system must be secured
with additional safety devices (safety edge, etc.).
Werkseitig mit fester Drahtbrücke ausgestattet. Durchtrennen erhöht
die Arbeitskraft an der Steuerung.
SPEED
Factory-equipped with fixed wire jumper. Cutting through increases the
