PosiDRIVE Security Gate Operational Overview
The PosiDRIVE Security Gate is a low-maintenance security gate, with a
microprocessor-based controller that protects roadways up to 20 feet (6 m). The
PosiDRIVE gate has a variable operating time, from 1.5 to 6 seconds, depending on the
length of the gate arm. The gate is capable of operating in an ambient temperature of
-30°F (-34°C) to 140°F (60°C) without any adjustments. It can be configured as a right-
hand or left-hand flange gate without any additional hardware.
The PosiDRIVE Security Gate works with several types of vend devices, such as vehicle
detection loops, card reading devices, or ticket issuing devices. The gate controller
inputs support both manual and automatic operation.
Manual Operation
For manual operation a toggle switch is wired into the Raise/Lower input on the gate
controller (Figure 2.3, on page 24). When the toggle switch is placed in the “raise”
position (i.e., the circuit is completed), the gate arm raises and remains in the up position
until the toggle switch is moved to the “lower” position.
Automatic Operation
For automatic operation, one or more vend devices are wired into the Vend input on the
gate controller (Figure 2.3, on page 24). Depending on the vend device(s), the lane runs
in one of the following modes:
■“Free Mode” on page 3
■“Pay Mode” on page 4
■“Pay/Free Mode” on page 5
For all automatic operation modes, a vehicle detection loop that resides under the gate
arm (loop B) is wired into the B Presence input on the gate controller. The gate
automatically lowers when the patron pulls off of the loop B.

PosiDRIVE Security Gate ZMA-330, Ver. 6 PosiDRIVE Security Gate Operational Overview • 3
Free Mode
Free mode is used in a single-direction lane through which a patron enters or exits the
facility free of charge. This mode requires two vehicle detector loop inputs: loop A and
loop B. When a vehicle pulls onto the loop A, the gate arm raises. The gate arm lowers
after the vehicle clears loop B.

Pay Mode
Pay mode is used in a single-direction lane in which controlled access is required to
enter or exit the facility. This mode requires a vehicle detection loop (loop B) and a
vend-device such as a card reader or a switch that a booth attendant uses to raise the
gate. The gate arm lowers after the vehicle clears loop B.
Note: An additional loop (loop A) may be used to enable the vend device, for
example, the lane may contain a ticket issuing device that is activated when the
patron pulls onto loop A.

Pay/Free Mode
Pay/free mode is used in a dual-direction lane. It requires two vehicle detection loops
(loop A and loop B) and a vend-device such as a card reader. In the free direction,
vehicle presence on loop A vends the gate. In the pay direction, the vend-device vends
the gate. In either direction, the gate arm lowers after the vehicle clears the loop B.

Power Failure Detection
The PosiDRIVE controller is able to sense when there is a power failure. If the
controller is programmed to raise the gate arm during a power failure, the controller uses
the power from backup battery assembly to raise the gate arm automatically. The gate
arm stays in the up position until the power is restored.
Note: If the controller is not programmed to automatically raise the gate, the gate must
be raised manually. See “Locking, Unlocking, and Advancing the Gate Arm” on
page 49.

■“Electrical Components” on page 10
■“Gate Arm” on page 13
■“PosiDRIVE Controller” on page 14
Gate Enclosure (Cabinet)
Federal APD, Inc. builds the PosiDRIVE gate enclosure using 0.090 inch galvanized
steel. The enclosure is weather resistant and allows proper operation in all weather
conditions and temperatures ranging from -30°F (-34°C) to 140°F (60°C). Louvres on
the back and cutouts on the four bottom corners of the enclosure provide air circulation,
thus preventing excessive moisture buildup.
The enclosure is 15 inches W x 16 inches D x 42 inches H (38 cm W x 41 cm D x 107
cm H), finished in yellow or white powder coat paint. The enclosure consists of two
pieces, a base and a removable cap. The base houses the power supply and electronics
package as well as provides the main structure of the enclosure. In addition, the base
provides reinforced flanges for installation, hookup points for the mainsprings, and
mounting provisions for the drive mechanism. Figure 1.4 illustrates the main
components of the gate enclosure.
The enclosure cap is a removable piece that provides easy access to the drive
mechanism without disrupting the operation of the gate. Inspection and maintenance can
be performed easily by removing the enclosure cap. It is secured by four draw latches to
the base, requiring no tools to remove or install. See “Removing the Enclosure Cap” on
page 16.

Figure 1.4 Enclosure Components
Mechanical Components
The PosiDRIVE gate is powered by a 150 watt, 24 VDC brushless DC gear motor.
The motor is connected directly to a fully sinusoidal four-bar drive mechanism. A
sinusoidal mechanism has the distinct advantage of providing smooth, progressive
acceleration and a mechanical advantage at the limits of travel, where it is needed most.
This arrangement eliminates the need for Vee-belts and their associated maintenance.
One advantage of a brushless DC motor is that the gate can adjust the speed of the entire
system depending on the size of the arm installed. Therefore, the same motor and
gearbox can be used in all situations, allowing the flexibility of using any size gate arm.
Another advantage to the brushless DC motor is the ability of the gate to know where
the gate arm is at all times. The motor provides an output that is monitored by the
controller. The controller interprets the signals to determine arm position and speed.
Using this information, the PosiDRIVE gate operates like a full servo system, providing
benefits such as not requiring mechanical contact to limit its travel, no limit switches,
and an extremely sensitive collision detect system.
The PosiDRIVE gate uses as many as four internal extension mainsprings to
counterbalance the weight of the gate arm. The number of mainsprings and their
adjustment must be properly set at the time of installation in order for the gate to
function properly. When correctly set, these mainsprings offset the torque on the
mechanism created by the weight of the arm, providing a safe, balanced system which
greatly reduces the power required by the motor and increases the efficiency of the gate.

Drive Mechanism
The drive mechanism in the PosiDRIVE gate is a direct drive, sinusoidal mechanism.
This system provides a substantial mechanical advantage for the motor at the beginning
and ending of a cycle when it is most needed. The result of this is that when the gate is at
the extreme limits of travel, in the “full down” or “full up” position, the mechanism is
“locked” and cannot be manually advanced by pushing the gate arm. In other words, at
the full up and full down positions, the mechanism cannot be driven or advanced by any
torque applied to the mainshaft. When servicing the PosiDRIVE gate, you must be
aware of this.
There are times, such as when setting the mainsprings, when you must operate the
mechanism by hand, using the gate arm. It is also necessary at times during this
procedure and others to ensure that the linkage is in the fully locked up position for
safety. Raising the gate arm by hand will NOT bring the linkage into this position. It will
bring it closed, but it will not be fully locked.
In order to lock the mechanism, you must always advance the mechanism by hand for
the last few degrees of travel. That is, if you raise or lower the arm by hand to what feels
like the limits of its travel, the mechanism still must be manually advanced a small
amount to ensure that it is in the locked position. If the mechanism is already locked,
either up or down, then it becomes impossible to get it out of this position by moving the
gate arm. The mechanism must be manually advanced out of the locked position before
moving the gate arm. This is a side effect of the sinusoidal linkage and the variable
mechanical advantage the system provides.
For instructions on manually advancing the mechanism into and out of the locked
positions, see “Locking, Unlocking, and Advancing the Gate Arm” on page 49.
Electrical Components
The use of a 24 VDC motor in the PosiDRIVE gate provides several electrical benefits.
First, by using a low (non-hazardous) voltage throughout the system, the risk of shock to
service personnel is greatly reduced. The PosiDRIVE gate utilizes a universal input 24
volt power supply. This supply can accept input voltages anywhere from 85 VAC to 264
VAC at 50 or 60 Hz. This allows the PosiDRIVE gate to be installed into virtually any
voltage environment without modification, providing maximum flexibility. The
nameplate rating for power consumption is 2 amps for 115 VAC and 1 amp for 220
VA C .
The PosiDRIVE gate is also equipped with a backup battery assembly, which provides
power to the controller and motor in the event of a power failure to allow the
PosiDRIVE gate to raise the arm. It is not intended to operate the gate in a power failure
mode, but just to provide the option of raising the gate to allow patrons to exit. It also
does not power any loop circuits. Automatically raising the gate during a power failure
is a configurable option. See “Setting the DIP Switches” on page 42.

PosiDRIVE Security Gate ZMA-330, Ver. 6 PosiDRIVE Structural Overview • 11
The PosiDRIVE gate can detect a line power failure and will wait (operating on battery
power) for a period of 10 seconds before raising the arm. This eliminates false responses
to transient (short term) power glitches. On detection of the return of line power, again a
delay of 10 seconds is provided before normal operation is resumed. The backup battery
assembly has ample power to provide this feature for several years before replacement.
Figure 1.6, on page 11 shows the PosiDRIVE gate electrical components. Component
descriptions follow the illustration.
Figure 1.6 Electrical Components
The door safety switch disconnects power to the motor under ALL
circumstances. If the door safety switch is bypassed (not normally
recommended) and the circuit breaker switch is turned off for any
reason, after 10 seconds, the gate activates under battery power and
raises the arm. The powerful drive mechanism can cause serious
bodily injury. Do not bypass the door safety switch unless absolutely
necessary.

The door safety switch disconnects power to the motor
under ALL circumstances. If the door safety switch is
bypassed (not normally recommended) and the breaker
switch is turned off for any reason, the system will respond
to this as a line power failure. After 10 seconds, the gate will
activate under battery power and raise the arm. Use
extreme caution when servicing the gate and be aware of
this condition. This is why the door safety switch should not
be bypassed unless absolutely necessary.
