Connecting the temperature monitor
When MKE motors are used in potentially explosive areas, the motor
temperature monitoring must be done in conjunction with Rexroth
Indramat drive controllers DKC, HDD or HDS.
The PTC resistors for the motor temperature evaluation are connected
according to the appropriate wiring diagrams of the drive controllers c
Caution!
Temperature evaluation of the motors can be done only
in conjunction with Rexroth Indramat drive controllers
Þ Connectors [1] and [2] of the PTC resistor must be
connected to the temperature monitor of the drive
controllers [TM+ ; TM-]!
MKE motors correspond to temperature class T4 according to EN 50014
:1992 (European Standard). Therefore, the highest permitted equipment
surface temperature is £ 135 °C. The triple PTC resistor installed in MKE
motors, together with the evaluation circuit of the drive control devices,
ensure a reliable and safe over-temperature switch-off.
