OPERATING MANUAL 4. MOUNTING OF MACHINE
ThyssenKrupp Aufzugswerke GmbH 35 Issue 06.2004
For operating voltage of magnet coils (direct current acc. to
DIN IECE038) see name plate at the brake body.
Connection and corresponding type of brake see table Technical data
chapter 3.4.
When the brake ERS VAR09 SZ1700 / 1700 is connected, make sure that
the necessary overexitation is always maintained. Disregard may affect safe
and quick operation! No overexcitation possible with brake type ERS VAR09
SZ1700 / 1250.
Note: when disconnecting the brake coils alternative power supply is
recommended. Direct power supply necessitates protection of the coils
against the risk of transient overvoltage acc. to VDE 0580.
Details on connection of connector plugs at the brake line ends see fig. 14
and chapter 8.3, Manufacturer's instructions (Warner) point 5.2.1.
Miniature fuse: the fuses in the power supply lines are to be adapted to the
customer's power supply.
Connection temperature monitoring brake:
The PTC thermistor detectors are series-connected (core grey/grey) at the
factory at the brake terminal box (terminal 5-7) via a screened cable. See
terminal assignment and connections at terminal box (fig. 11) and connection
assignment for conductor in fig. 14.
Terminals "Th" are to be connected to a PTC thermistor tripping device by
the customer. The voltage applied shall not exceed 2.5V.
See to it that the distance to all revolving parts is observed by persons laying
connecting cables.
Corresponding counter measures are to be made.
Do not use the same cable duct for connecting lines used for temperature
monitoring and brake test and motor connection line.
Connection release monitoring brakes:
Microswitches are attached at the coil body of the magnet brake. A pre-set
and pre-assembled switch per brake circuit each monitors the brake
condition (opened/closed). The setting shall not be changed.
When replacing make sure that the switch setting is in accordance with the
instructions in chapter 7.3.
Check the switches for proper setting and correct function.
