Operation permissible in switchgear cabinet with degree of protection
IP 54 only!
Application
The contactor safety combinations can be used in EMERGENCY-OFF circuits
and for monitoring protective devices (e.g. protective screens).
Functions and connections
The internal control circuit of the contactor safety combination is designed
according to DIN EN 60204, Part 1 (VDE 0113, Part 1), para. 9.4.2.2, so that
in the case of a fault in one of the contactor relays the function of the safety
circuit is maintained. The supply voltage must meet the requirements of the
DIN EN 60204 (VDE 0113, Part 1) (the terminals “L-/N; A2“ must be connec-
ted to that side of the control current circuit which is linked to the protective
conductor system).The contacts of the contactor relays are checked for pro-
per opening and closing in every ON and OFF cycle of the machine to be swit-
ched. This is, for instance, done by
- connecting and disconnecting the control voltage with the main
switch,
- activating and deactivating the EMERGENCY-OFF unit
- opening and closing of the protective screen.
For circuit diagrams, see:
Fig. III: EMERGENCY-OFF circuit
Fig. IV: Protective screen monitoring (A=door open; B=door closed)
Fig. V: EMERGENCY-OFF with expansion module (no delay)
Fig. VI: EMERGENCY-OFF with time-delay module
For internal circuit diagrams, see Low-Voltage Control Equipment,
Switchgear and Systems Catalog.
Note: The units are tested by the BIA. The external control circuit connec-
tions are shown for example only; the actual connections must be defined
by the user on the basis of a risk assessment.
Further applications available upon request.
Installation
For dimension drawings see Fig. I (dimensions in mm).
Minimum clearances from earthed parts on the sides: 3 mm (see Fig. IIa).
Connection see Fig. IIb.
Cover the contactor safety combination during installation if foreign
particles, such as swarf, can fall onto it. Install contactor safety combi-
nations in a housing if they are exposed to dirt, dust or aggressive
atmospheres.
Permissible operating position: any
Cleaning: Remove dust with a vacuum cleaner
Operation
Operating states of the unit:
“READY“ (3TK2803/2804) indicates that voltage is applied to the unit, pro-
vided that the contacts of the EMERGENCY OFF pushbutton or door safety
switch are closed.
“ON“ lights up, when the ON button is pressed and the enabling circuits are
switched through.
“FEEDBACKCIRCUIT“ (3TK29.3/2907) lights up when the ON button is
pressed and the enabling circuits of the expansion modules are switched
through.
