6.3. Other functions
In the event of a software error occurring, the inherent processor watchdog will repeatedly attempt to restart the
Switching Amplifier BS805, this involving constant opening/closing of the relays SP1 and SP2.
Zero drifts on the internal amplifier are cyclically corrected.
The function of the Switching Amplifier BS805 is not impaired by errors occurring on downstream devices.
Coercive fusing of relay SP2 can be set by means of key code ‘251’ as follows: SP1 lies 0…2mA above SP2.
Accordingly, SP1 monitors SP2 (the latter normally being set with a time lag) and is immediately de-energised
whenever a short and high load peak occurs
7. Commissioning
7.1. Mounting
The BS 805.01 and BS 805.11 appliances are intended to be wall-mounted using two M5 screws. The drilling patterns
for BS 805.01 (163 x 52) and BS 805.11 (238x52) will be found under 3.
Appliances BS 805.21 are designed for mounting on a standard rail.
7.2. Connection
The cables for the sensor, the supply voltage and the signal output are to the strip_X1: to attach. Protective
conductors of the discharges for the switching signals are to be attached absolutely to the strip_X12: PE
Standard contacting of cable shield to contact clip

cable jacket and shield dismantle

cut around the cable jacket 15mm behind the end, do not remove however yet

pass through the cable

cable jacket removal

draw back the cable until the connection between cable shield and contact clip is existent

tighten
Contacting of cable shield with thin cables without cable sheath :

cable jacket dismantle

roll up the shield over the cable jacket approx.15 - 20 mm

pass through the cable until the connection between cable shield and contact clip is existent

tighten
