BM-1600 (Rotary Encoder Based)
The BM-1600 is a time-based brake monitor that utilizes a high resolution rotary encoder and controller to measure the brake stopping time in milliseconds and also the RPM of the press. The rotary encoder is attached to the subject machine and is driven on a 1:1 ratio by the power press crankshaft. The brake stopping time of the machine will be displayed on every stop and can be easily read on the bright red light emitting diode (LED) display on the front panel of the unit. The RPM/ of the machine will be displayed during the machine cycle.
Brake Warning Indicator
Yellow light illuminates when the setpoint is exceeded. Excellent input for the press operator and for maintenance.
Drive Failure
Red LED illuminates when the pulses from the encoder disappear while the brake remains released.
Brake On
Yellow LED illuminates when power to the dual solenoid valve drops out.
Ready
Green LED illuminates when all systems are go.
Not Ready
Red LED illuminates when the brake monitor safety relays have dropped out (i.e., drive failure, internal failure, etc.)
+/- Pushbuttons
The +/- pushbuttons are used to set the time values in milliseconds for the brake warning and the brake limit setpoints.
Brake Failure Indicator
Red LED illuminates when the actual brake stopping time exceeds the programmed brake limit setpoint.
Stop Time
Displayed in milliseconds after every stop in machine cycle and the red LED is illuminated.
RPM/SPM
Displayed during each press cycle when the red LED is illuminated.
Brake Warning Time
Displayed in milliseconds when the red LED is illuminated.
Brake Limit Time
Setpoint is displayed in milliseconds when the red LED is illuminated.
