Babbitt Liquid Level Gauge - Manual (Page 10)

MOUNTING
The MLS-9EX are simply mounted to the level gage chamber using stainless steel band clamps.
The switch must be originated properly, switch is marked “TOP”. It is adjustable the full length of the
level chamber. To set up desired contact state follow the steps below:
RISING LEVEL ALARM
Common (NC) (NO)
TERMINAL 2 3 1
FALLING LEVEL ALARM
Common (NC) (NO)
TERMINAL 2 1 3
After the switch is mounted and wired, it needs to be set to the desired state for rising or falling
level as noted above. This is easily accomplished by either manually pushing the float past the
highest switch or filling the gage chamber with fluid until all switches are properly set.
Note: Refer to Appendix B for pump up/pump down instructions.

The 10-EX level switch is a DPDT high current device used to control pumps, alarms, solenoids,
etc. The 10-EX is a cam-activated switch designed for use with the LG series magnetic level
