Nordson Rhino SD2CE User manual

RhinorSD2CE/XD2H Drum Level Detect Module
Instruction Sheet: 1085716A
E2008 Nordson Corporation Issued 2/08
Description
See Figure 1. The Drum Level Detect Module uses roller
plunger limit switches on guide rails to monitor the
distance between the bottom of the follower/platen 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 three conditions during the
downward movement of the follower/platen:
SFollower/Platen in drum
SDrum Low
SDrum Empty
Refer to the Adjusting Limit Switches section for more
information on setting the limit switches.

Table 1 Limit Switch Descriptions
Switch Description
Follower/Platen
in Drum (A) Switches two-hand lowering mode to normal automatic lowering mode. This switch is not factory set. It must be set before the system is put into service.
Drum Low (B) Factory set to activate when the bottom of the follower plate/platen is 7 inches from the drum
support rails.
Drum Empty (C) Factory set to activate when the bottom of the follower plate/platen 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/platen bottoms out.
