SMU Replacement Parts (Mechanical Side)
PROBLEM: The SMU will not make a measurement (take a
sounding)
CAUSE/SOLUTION:
1. (All models) Lock-out feature is “active”. Remove "lock-out"
signal from the lock-out terminal block.
2. (RS-485) The address of the SMU and the operator inter-
face channel do not match, or there are multiple SMUs with
the same address. Create a unique address for each SMU
on the network and ensure they match-up with a operator
interface channel #.
3. (RS-485) The network termination switches are improper-
ly set. Verify that only the devices on the physical ends of
the network have the network termination switches “ON”,
and all others are “OFF”.
4. (Analog) The automatic timer is not activated. Verify that
the parameter AutoTime is “ON” if automatic measurement
cycles are desired.
PROBLEM: The SMU reports an “Error” after a measure-
ment cycle is completed
CAUSE/SOLUTION:
1. (Return Error) The plumb bob did not travel as far when
ascending as it did when descending. Determine if plumb
bob is trapped in material. Request another measurement.
A subsequent “motion” error confirms an entrapment. A
subsequent “index” error indicates that plumb bob has
freed itself. Request another measurement and errors will
likely cease.
2. (Index Error) The plumb bob did not travel as far when
descending as it did when ascending. Determine if mount-
ing is causing the plumb bob to return to an inconsistent
location at the start/socket position.
3. (Motion Error) The plumb bob did not travel a far
enough distance when measurement was requested.
Consider the following possibilities:
- Plumb bob is trapped in material
- Plumb bob is stuck to mounting surface
- Cable is broken
- Cable is restricted in wiper seal
- Cable is damaged
PROBLEM: The plumb bob gets stuck in the socket
CAUSE/SOLUTION:
1. Material build-up may be causing plumb bob to “cling” to
the socket. Turn “ON” the Descend-Assist feature through
the ConfigureSensor app in the MISC SETTINGS section.
See Pg. 10 (RS-485) or Pg. 13 (Analog) of this document.
PROBLEM: The SMU measurement is not accurate
CAUSE/SOLUTION:
1. Cable length is too short for application. Replace cable
with suitable length.
2. Wiper seals are creating excessive drag resulting in pre-
mature reversing of plumb bob. Clean or replace
wiper seals.
3. Cable is slipping on measuring wheel due to the lubricity of
the material being measured. Consult factory.
4. Cable is damaged (kinked, frayed) somewhere through its
length resulting in premature reversing of plumb bob.
Replace cable.
5. Cycle Limit function CycLimit is causing plumb
bob to reverse before reaching material surface.
Configure CycLimit value to suit application.
