Safety relais
Safety contact edge SENTIR
edge
:
A maximum of 5 SENTIR edge devices can be connected in series. The maximum total length of the SENTIR
edge must not exceed 100 m.
The length of a SENTIR edge can be up to 25 m.
The total line length of the series-connected SENTIR edge must not exceed 25 m.
Safety contact bumper SENTIR
bumper
:
A maximum of 5 SENTIR bumper devices can be connected in series. The maximum total length of the SENTIR
bumpers must not exceed 15 m.
The length of a SENTIR bumper may be up to 3 m.
The total line length of the series-connected SENTIR bumpers must not exceed 25 m.
Safety contact mat SENTIR
mat
:
A maximum of 10 SENTIR mats can be connected in series. The maximum total surface area must not exceed
10 m2.
The size of a SENTIR mat can be up to 1350 x 2350 mm.
The total line length of the series-connected SENTIR mat must not exceed 25 m.
Before connecting the series-connected sensors, it is recommended to measure the resistance value of the
wiring. In the case of non-operated sensors the resistance must be 8.2 kΩ ± 500 Ω. If the sensor is operated,
the resistance must not exceed 500 Ω.
9.4 Connection of control circuits
Connect the control circuit to be monitored to the
13
and
24
terminals. If the switching contacts are redundantly
continued, the factory-inserted bridge between the
14
and
23
terminals must be removed.
In the event of any redundant use of the switching contacts only voltages with the same potential
may be connected. The use of different voltage potentials does not correspond to any intended
use within specifications.
Depending on the nominal current, the control circuits are to be protected by a corresponding
fuse, or the nominal current on the control circuits must be limited to the maximum value by
means of other measures.

.5 Connection Reset
For the operating mode “manual reset” the necessary reset switch must be connected to the
Z1
and
Z2
terminals.
9.6 Connection of signaling contact
The 31 and 32 signaling contact only serves as an auxiliary contact (signaling, display etc.) and must not be
integrated into the safety circuit.
The signaling contact may only switch extra low voltages (24V). The switching of low voltages
120 V (230V) is not permissible.
Installation and electrical work must be performed by authorized electricians.
Wrong installationcan cause hazardous conditions.
The manufacturers liability will erase in any case of non-compliant or deliberate abuse.
