Rockwell Automation 1336_S_F_T Allen-Bradley Dynamic Braking - Manual (Page 22)

Heavy Duty Dynamic Braking 22
1336-5.64 — July, 2005
Brake Fault Contact Monitoring For all brake ratings a fault contact has been provided to provide a remote
output signal to an Allen-Bradley 1336-MOD-L3, L6 or PLC. Should a
brake fuse fail, the brake thermostat trip (or for KB050 & KC050 units the
brake enable signal be lost), the brake fault contact will open.
Interconnection wiring for remote brake monitoring is provided in the
Wiring Schemes.
Brake Fuses All dynamic brakes are internally fused to protect brake components. When
replacing brake fuses, use only the type and size specified below.
Brake Module Jumper Settings For the Recommended Brake Configurations shown on the previous page as
well as the interconnection diagrams shown on the following pages, there
can be only one master brake to control dynamic braking. When multiple
brakes are used, only one brake can serve as the master brake to control the
remaining slave brakes.
Master Brake Module Jumper Settings
For the master brake, leave slave/master
jumper W1 factory set to master — Between
jumper positions 2 & 3.
Slave Brake Module Jumper Settings
In each slave enclosure, reset jumper W1 to
slave — Between jumper positions 1 & 2
Input Voltage Jumper Settings
For KB brakes, remember to set jumper W2
in all enclosures to correspond to the
nominal drive input voltage. Setting the
jumper between positions 1 & 2 will select
an input voltage of 415/460 volts. Setting the
jumper between positions 2 & 3 will select
an input voltage of 380 volts.
KA and KC brakes do not have input voltage
jumpers.
