Pneumatic Level Detect Modules
Part 1603025--01
E2012 Nordson Corporation
Description
See Figure 1. Level Detect modules use roller plunger
limit switches on guide rails to monitor the distance
between the bottom of the follower and the base surface
of the bulk unloader frame.
The actuating rod connects to the bulk unloader
crossover bar. It actuates each roller plunger on the limit
switches during the downward movement of the
follower/platen.
The assembly detects two conditions during the
downward movement of the follower:
SFollower in drum
SDrum Empty
Refer to the Adjusting Limit Switches section for more
information on setting the limit switches.

Table 1 Limit Switch Descriptions
Switch Description
FollowerinDrum(A) When activated, switches Manual lowering mode to Automatic lowering mode. This switch is
not factory set. It must be set before the system is put into service.
Drum Empty (B) Factory set to activate when the bottom of the follower is 1.5 inches from the drum support
rails. This switch can be adjusted to minimize material waste. Adjust this switch for drums
with the tallest seam height to ensure that the follower/platen does not bottom out before the
switch is activated. The pump will cavitate and may cause damage to the system if the
follower bottoms out.
