1.0 Introduction
Th Solit l®Vibrating Rod L v l Switch provid s r liabl
l v l d t ction of bulk solids and powd rs. This compact,
int gral switch is suitabl for high or low l v l d t ction
in hopp rs and silos. It may also b us d for plugg d
chut d t ction.
Th rugg d, singl -pi c prob is suitabl for us in a
vari ty of powd rs or granular mat rials with a minimum
bulk d nsity of l ss than on pound p r cubic foot.
1.1 Principle of Operation
Th Solit l®rod vibrat s at a 350 Hz fr qu ncy. Wh n
m dia mak s contact with th rod, th vibration is damp-
n d. Th att nuation of th vibration is d t ct d by th
int gral mount l ctronics, changing th status of th r lay.
2.0 Installation
2.1 Unpacking
Unpack th instrum nt car fully. Mak sur all compo-
n nts hav b n r mov d from th packing mat rial.
Insp ct all compon nts for damag , and r port any
conc al d damag to th carri r within 24 hours.
Ch ck th cont nts of th carton, making sur it agr s
with th packing slip and th purchas ord r. V rify that
th mod l numb r imprint d on th nam plat match s
th numb r on th packing slip and th purchas ord r.
R port any discr panci s to th factory. Ch ck and r cord
th s rial numb r for futur r f r nc wh n ord ring parts.

2.2 Mounting
Prior to installation, it is r comm nd d that th unit b
calibrat d using a sampl of th m dia to b m asur d.
Refe to Calib ation, Section 2.5.
IMPORTANT: Handl th instrum nt with gr at car ,
sp cially th prob . Any impact on th prob can damag
th vibration syst m.

Th SOLITEL switch is mount d to th v ss l using a
11⁄2" NPT thr ad d conn ction.
• Ensur that th tip of th prob is locat d at th d sir d
switching point giving consid ration to th slop angl of
th mat rial.
• Th switch may b install d v rtically or horizontally
(at a downward angl ) as shown in Figur 1 on pag 3.
• Avoid mounting th s nsor in a r c ss wh r buildup
could damp n th vibration. S Figur 2.
• Do not cut or b nd th vibrating rod.
IMPORTANT: A d fl ction plat is r quir d wh n th
prob is xpos d to falling mat rial, collaps d arch, or, in th
cas of a low l v l switch, wh n th drag forc of th mpty-
ing mat rial xc d th sp cifications. Th d fl ctor can b
a baffl plat or angl iron (11⁄2" ×11⁄2" ×1⁄8") locat d 4 to
6 inch s abov th rod. S Figur 3.
Obs rv th sp cifications for b nding forc (F),
torqu (M), and pull forc (F) as indicat d b low:
S Figur 4.
Standard: F = 100 pounds (445 N)
M = 63 foot pounds (85 Nm)
Ext nd d Rigid: M = 63 foot pounds (85 Nm)
Wh n using an xt nd d l ngth v rsion for low l v l
alarm, mount th prob abov th outl t of th v ss l to
avoid th prob b ing dragg d along by th outflowing
mat rial.
2.3 Electrostatic Discharge (ESD)
Handling Procedure
MAGNETROL l ctronic instrum nts ar manufactur d
to th high st quality standards. Th s instrum nts utiliz
l ctronic compon nts which may b damag d by static
l ctricity pr s nt in most work nvironm nts. Th
following st ps ar r comm nd d to r duc th risk of
compon nt failur du to l ctrostatic discharg :
1. Ship and stor circuit boards in anti-static bags. If an
anti-static bag is not availabl , wrap board in aluminum
foil. Do not plac boards on foam packing mat rials.

2. Use a grounding wrist strap when installing and
removing circuit boards. A grounded workstation is
also recommended.
3. Handle printed circuit boards only by the edges. Do not
touch components or connector pins.
4. Ensure that all electrical connections are completely made
and none are partial or floating. Ground all equipment to
a good earth ground wiring.
2.4 Wiring
Manually position the housing in the correct direction to
allow for easy wiring. The housing can rotate one full turn.
1. Make sure the power supply is turned off.
2. Unscrew and remove housing cover.
3. Connect power leads to the proper terminals. To simplify
wiring, the terminal strips may be removed from the
module by lifting the front edge of the terminal block.
Refer to Figure 5.
a. 120 VAC – Connect the “hot” wire to terminal marked
L1 and the “neutral” to terminal L2/N. There is no con-
nection to the center terminal.
b. 24 VDC – Connect wires to terminals (+) and (-). There
is no connection to the center terminal.
4. To ensure optimum noise immunity, attach the ground
wire to the green grounding screw inside the housing base.
Caution: On 4 VDC units, the negative terminal of the power
supply is isolated from ground and proper earth grounding
of the power supply shield wire is necessary for noise
immunity.
5. Connect relay terminals. Refer to Figure 6.
6. Set the fail-safe umper as described in the table on page 6.
For alarm applications, it is recommended that the
de-energized status of the relay be used as the alarm status.
This allows detection of power failure as an alarm status.
7. Wiring is complete. Replace the housing cover.
8. Apply power to the unit.

2.5 Calibration
Ensur that th fail-saf jump r is install d in th prop r
position as d scrib d in Tabl 1. Th LED will show

condition. T st th op ration of th switch by holding,
and th n r l asing th vibrating rod; th LED will
chang color.
Th s nsitivity of th switch can b chang d using th
d nsity adjustm nt scr w. Not that this adjustm nt scr w
has 270 d gr s of rotation. Do not rotat past th stops.
NOTE: If the adjustment is too sensitive, the switch may detect
even slight residue of material rather than level.
Prior to installation, it is r comm nd d that th unit b
calibrat d using a sampl of th m dia to b m asur d.

3.0 Reference Information
3.1 Troubleshooting
SOLITEL is a simpl and r liabl d vic . How v r, car
must b tak n to avoid impacting or damaging th vibrat-
ing prob .
In th v nt th SOLITEL stops vibrating, th following
proc dur will id ntify if th probl m is with th l ctron-
ic modul or with th s nsor:
Disconn ct th wir s going to th s nsor. (T rminals 3, 4,
and 5). Th following giv s th xp ct d voltag rang
b tw n th s nsors.
If th s voltag r adings ar not obtain d, th l ctronics
ar d f ctiv and n d to b r plac d. If th s voltag s ar
m asur d, th probl m is with th s nsor.
NOTE: The probe and electronics must be matched to ensure
proper operation. Use the following procedure to match
the electronics and the vibrating probe:
1. Conn ct th wir s from th s nsor to t rminals 3, 4, 5.
Th r will b two wir s of th sam color and on wir of
diff r nt color. Th two similar wir s go to t rminals 4 and
5; th singl wir go s to t rminal 3.
2. If th pot ntiom t r is lab l d “d nsity” turn to th low
position – if lab l d “s nsitivity” turn to th high position.
Not this pot ntiom t r has a 270 d gr turn.
3. Apply pow r to th l ctronic modul .
4. Turn th l ctronic modul ov r.

5. Connect a digital multimeter between points MP5 on the
back of the module and ground connection terminal 3 on
the electronic module) or the body of the vibrating probe.
See Figure 7 on page 7.
6. Adjust potentiometer P2 on the rear of the electronic mod-
ule to obtain a voltage between 0.4 volts and 1.0 volts. The
reading should be as close to 1.0 volt as possible.
7. Grasp the vibrating section of the sensor with your hand.
The vibration should stop and the relay will change state.
8. Remove your hand from the sensor. The relay will
change state.
9. The electronic module and probe are now matched.
