Safety instructions

1

These devices and their accessories may only be operated in compliance with the operating instructions (intended use)!
These devices and their accessories may only be commissioned by trained and qualified personnel.
These devices may only be operated with the intended operating voltages and parameters.
If malfunctions occur that cannot be rectified, shut down the device and send it in for repair.
These devices are only allowed to be repaired by the manufacturer. Tampering and alterations are not permitted. This will invalidate all guarantee and
warranty claims.

Mechanical mounting in the switch cabinet

2

The SMA / SMA 2 / SMA 220 is mounted on a 35 mm mounting rail acc. to EN 50 022 in the switch cabinet.
The terminals are pluggable and coded.

Electrical connection

3

The loop connection wiring to the loop detector must be twisted at least 20 times per meter.
Please ensure the unit is wired properly with correct input voltage and all terminals are connected according to the wiring diagram on the label.

Basic functions 0 (see Table 4.11a for settings)

Parameters
1: Door and gate The assigned output relay picks up when the loop is activated and drops out when the loop returns to a non-activated condition.
2: Barrier The assigned output relay picks up when the loop is activated and drops out when the loop returns to a non-activated condition.

: Quiescent current The assigned output relay drops out when the loop is activated and picks up again when the loop returns to a non-activated condition.

3
4: Direction logic Output 1 switches if an object moves from loop 1 to 2. Output 2 switches if an object moves from loop 2 to 1. Both loops must be

activated for a short time. The outputs are reset again when loop 2 returns to a non-activated condition. Both loops must have re­turned to a non-activated condition for another direction detection.

0: Loop 2 Loop 2 can be deactivated in a 2-loop device.

Relay response to malfunctions (see chapter 6 Troubleshooting):

1.Door/gate
systems

4.3

Time functions 1 , time unit 2 and time factor 3 (Einstellungen siehe Tabelle 4.11a)

A malfunction causes
the output relay to be
released. The alarm
relay drops out.

2. Barrier

The relay picks up when the
loop is activated and drops
out when the loop is exited.

Activation pulse:
The relay picks up when the
loop is activated and drops
out again after the time t.

Sensitivity 4 (see Table 4.11a for settings)

4.4

A malfunction causes
the output relay to pick
up. The alarm relay
drops out.

On delay:
The relay picks up after the
time t when the loop is acti­vated and drops out when
the loop is exited.

Impulse by leaving the loop:
By leaving the loop,
the relay picks up after
the time t, relay drops out.

3. Quiescent
current

A malfunction causes
the output relay to be
released. The alarm
relay drops out.

Off delay:
The relay picks up when the
loop is activated and drops
out after the time t when the
loop is exited.

Max. presence:
he relay picks up when the
loop is activated and drops
out again after leaving, but
at least after the time t.

4. Direction logic
(2-loop device
only)

A malfunction causes
the output relays to be
released. The alarm
relay drops out.

The sensitivity 5 (=Sensitivity) of the loop detector can be adapted in 9 stages: 51 = Lowest sensitivity, 59 = Highest sensitivity,
54 = Factory setting.

4.5

Automatic Sensitivity Boost ASB 5 (see Table 4.11a for settings)

ASB (=Automatic Sensitivity Boost). ASB is required in order to be able to recognise trailer drawbars after activation.

4.6

Frequency 6 (see Table 4.11a for settings)

Four different frequencies F1, F2, F3, F4* can be set in order to avoid interference when using several loop detectors.

4.7

Direction logic7 (see Table 4.11a for settings)
The direction logic function can only be used with a 2-loop device. Direction logic must have been set in the basic function (see chapter 4.2). Detection
can be performed from: ➝ Loop 1 to loop 2 ➝ From loop 2 to loop 1 ➝ from both directions

4.8

Output 2 8 (see Table 4.11b for settings)
In a device with 2 outputs, output 2 can be either activated or deactivated.

4.9

Protection against power failure 9 (see Table 4.11a for settings)

Note: The set parameter values are retained after a power failure, independent from the “Protection against power failure” function.
P 1 = Protection against power failure activated: The sensitivity is restricted to 1–5.

4 .9.1

Signal characteristics with protection against power failure active (Function 9 = 1)

For Activation (e.g. Barriers)

Basic function 0 = 2 Barrier systems

Output

For Safeguarding (e.g. Barriers, bollards)
