The following table lists the dielectric constants e

of some important materials. Due to the high

dielectric value of water, the fluctuations with

wood can be significant. Damp wood therefore is

registered much more effectively by capacitive

proximity switches than dry wood.

Electronic position switches LSE-Titan®

Switching point adjustable and variable

The switching point on electronic position

switches LSE-Titan is adjustable and variable. Two

high-speed and bounce-free PNP switching

outputs enable high switching frequencies.

The position switch is overload as well as

conditionally short-circuit proof and has

snap-action switching behaviour. This ensures a

defined and reproduceable switching point. The

switching point lies in the range from 0.5 to

5.5 mm (supplied as = 3 mm).

Adjustment to a new switching point is carried out

as follows:

Move the plunger from the original to the new

switch position. For this purpose, press the setting

button for 1 s. The LED now flashes with a high

pulse frequency and the new switching point is

retentively set.

In redundant structures, position switches

LSE-Titan just like electromechanical position

switches, achieve safety category 3 or 4 to

EN 954-1, Safety of machinery.

Note

This means that all the devices are also suitable

for safety applications designed for personnel or

process protection.

Command and signalling devices

Analog electronic position switches

Two types are available:

• LSE-AI with current output,

• LSE-AU with voltage output.

Analog, mechanically actuated position

switches directly linked with the world of

automation

Analog position switches LSE-AI (4 to 20 mA) and

LSE-AU (0 to 10 V) represent another innovation

in electronic position switches. Using them, it is

now possible for the first time to monitor the

actual position of a flue gas valve or an actuator

continuously. The actual position is converted in

analog fashion into voltage (0 to 10 V) or current

(4 to 20 mA) and then continuously signalled to

the electronics. Even objects of varying sizes or

thicknesses, such as brake shoes, can be scanned

and the results processed further.

Simple rotational-speed dependent control

systems of fan motors or smoke-venting blowers

signal the opening angle of the air damper

(e.g. 25, 50 or 75 %) and thus save power and

material wear. The analog position switches also

have a diagnosis output for further processing of

data. This means that the safe status can be

monitored and analysed at all times. The position

switch also has a self-test function. The outputs

Q1 and Q2 are constantly scanned for overload,

short circuit against 0 V and short circuit against

New combinations for your solutions

RMQ-Titan® and LS-Titan®

Actuating devices RMQ-Titan® simply snap

fitted

Another unique feature is the possibility to

combine control circuit devices from the

RMQ-Titan range with the position switches

LS-Titan. Pushbuttons, selector switches or

Emergency-Stop buttons can all be directly

snapped on to any position switch as operating

head. The complete unit then has at least the high

degree of protection IP66 at front and rear.

In addition, all the operating heads and the

adapter for accepting the RMQ-Titan actuators

have a bayonet fitting that enables quick and

secure fitting. Using the bayonet fitting, the heads

can be attached in any of the four directions

(4 x 90°).

a Operating heads in four positions, each

turned by 90°, can be fitted subsequently.

Rotary Switches

ON-OFF Switches, Main Switches, Maintenance Switches

ON-OFF switches, main switches

These switches can also be used as

switch-disconnectors for lighting, heating or

combined loads.

Main switches to IEC/EN 60 204 for rear mounting

switches with door interlock, padlocking feature,

finger-proof incoming terminals, N and PE

terminal, red thumb-grip handle (black, if

required), warning label.

If it is not clear which drive is associated with

which main switch, an additional maintenance

switch is required close to each drive.

Maintenance switches are fitted to electrical

machines or installations to provide safe working

conditions in accordance with the safety

regulations.

By attaching his own padlock to the SVB

padlocking feature, the electrician can protect

himself against anyone switching on without

authorization (a section “Circuit diagram

example for maintenance switches with a load

shedding contact and (or) switch position

indicator”, page 4-4).

Function

Load shedding: When

switching on, the main

current contacts close first,

then the contactor is

activated via the late-make

N/O contact. When

switching off, the contactor

is first disconnected by

opening of the early-break

contact, then the main

contacts isolate the motor

supply.

Switch position

indication: The position of

the switch can be signalled

to the control panel or

mimic diagram panel via

additional NO and NC

contacts.
