1 Application and short description
1.1 Application and Short Description
TMP tripping device MS 220 DA - MCB 112 PTC Thermistor Option B is designed as a passive option interface for Danfoss Frequency Converter series
VLT
®
. The MS 220 DA fulfils the requirements of the document P400 Platform
Identification of passive option
and will be recognized automatically by
the drive.
TMP tripping device is according EN 60947-8 (VDE 0660 part 0302). PTC-thermistor sensors according DIN 44081 and 44082 (VDE 0660 part 0303) can
be connected. The TMP tripping device can be used to protect electrical machines against inadmissible heating due to overload. With ATEX marking it
can also be used as protection device for explosion-protected motors in areas with explosive gas atmospheres Zone 1 (refer to marking G) and locations
with explosive dust atmospheres Zone 21 (refer to marking D). All functions in the TMP tripping device serve to protect non-explosive-protected motors
and explosive-protected motors in regular operation and in case of failure.
Approvals: marking see type plate on the device.
1.2 Connection Plan
1.3 Overview of Functions
The TMP tripping device MS 220 DA - MCB 112 PTC Thermistor Option B includes a tripping stage for PTC-thermistor sensors with save potential separation
from supply voltage and ground. The tripping function switches off the +24 V DC-voltage directly at the Safety Stop T37 of the drive. The PNP logic
output terminal X44/10 signals the status in case of failure. The TMP tripping device works according to the closed-circuit principle. The device trips in
case of short-circuit or line interruption.
The MS 220 DA needs +24 VDC supply voltage. The serial EEPROM enables the drive to recognize the built-in option module.
