Series 35 Temperature Monitor
3 digit LED display - 0-200 degrees C
The Series 35 Temperature Monitor is
a solid state device used for the indication and alarm on the
6 RTD's embedded
in the 3
phase motor windings (2 ea/phase)
The temperature set points for alarm and shutdown
are located on the rear of the instrument. The
3 digit
temperature indicator is
mounted on the front panel
with a 5 pt. selector switch. The indicator reads
point
PT (#1 probe), which is selected as the
hottest point. A
selector switch and
pushbutton
allow the other 5 points to be read on the meter. The instrument can be
supplied with inputs for 3 wire RTD's or for shorter distance
between monitor
and motor.
2 wire RTD connections can be used, thus requiring
only 6 wires and one common (7
total) from meter to monitor vs 18 wires
for 3 wire
RTD system.
*Note: A
8 point model is available which
monitors the 6 winding RTD's
and also the two end bearings

SMART-2
Motor Bearing/Winding Temperature Monitor
This instrument is ideal for monitoring and
protection of a motor end bearing over-heating problem.
The controller input is from a 100 Ohm platinum RTD sensor
located at each of the end bearings. It has two relay
outputs which are used to provide the customer of an
over-heating alarm condition and a second adjustable relay which
is set at a higher temperature to provide a relay contact for
the customer to use to shut down the motor before damage to
bearings. One instrument is required for each of the two
card bearings. Price: $ 195.00 each.

Model 15A-2 Alarm Controller
The Model 15A-2 Alarm Controller
 Module operates either from a thermocouple RTD,
or other millivolt or milliamp input signal. The output is a 12
amp 120/240 VAC relay SPDT dry contacts. When used with
a thermocouple, burnout and automatic cold junction
compensation are standard. The alarm unit
consists of a
temperature stable D.C. amplifier, a driver stage and power
supply. The alarm/control point can be set either by means
of a dial located on
the top of the module or a remote dial
w/6ft.Cord. Standard dial ranges are
0-400, 0-1000, 0-2000
degrees F/degrees C. |
|
The standard alarm will provide a contact closure when the temperature (or
other input)
exceeds that set on the set point dial. The relay contacts (SPDT)
are brought out to the
customer connection terminals to be used for operation of
a remote control device i.e.
indicator light, annunciator, power relay, power
relay coil, shunt trip/breaker, etc.
The standard alarm is furnished with a
non-latching mode of operation, but it can
also be furnished as a latching alarm
w/reset pushbutton either located on the top of the
unit or at the customer
connection strip for remote reset pushbutton operation (N.C. contact).
In the non-latching mode of operation, the output relay contacts will
automatically return
to the normal condition when the temperature drops back
below the set point temperature.
In the latching mode, the output relay contacts
will remain in the alarm condition even when
the operating temperature drops
back below the set point temperature and must be reset by
depressing
momentarily, the reset pushbutton. The pushbutton is either furnished on the
module
or is connected to terminals provided on the customer connection strip
for a remote pushbutton
supplied by the customer.

Customer Connections
1. Connect 120 VAC 50, 60 Hz AC power to customer terminals labeled HOT-NEXT.
(120 VAC)
2. Connect Type K Chrome-Alumel thermocouple to customer terminals labeled
3. Connect the heater load to the Normally Open (N.O.) Relay contact. This is
customer connection labeled N.O. and C. relay contacts.
*Note: The N.O. contact is closed below control point wh the process is cold
and will open to remove power from the heater when temperature exceed that set
on the control temperature dial. The relay contacts are rated at 5 amps 120 VAC.
4. The remote set point dial is shipped with the cable connected to the
customer terminal strip W(red), CW(white), and CCW(black)
5. The unit is shipped with a jumper across the remote reset terminals (this
jumper must remain for normal controller operation).
The Model 15A-2 single point RTD alarm is designed to monitor Motor Winding
Temperature by means of resistance temperature detector (RTD).
The monitor utilizes a 100 ohm at 0 degrees C. RTD sensor in the motor
winding or end bearing surface. The RTD is connected to terminals labeled S0 and
S2. The terminals labeled P1, P2, and P3 are not used for this application, (
these are used when the alarm set point potentiometer is mounted on a plate for
remote mounting by customer ). The set point dial reads 0-200 degrees C. and is
set at the temperature desired to protect the motor. When the temperature
reaches the set or the dial, the relay will operate and the contacts at
terminals C, N.C. and N.O. will transfer, i.e., the contact labeled N.C. will
close, when the alarm set point is reached.
Also available for 10 ohm and 129 ohm RTD’S.
The Model 15A-2 Thermocouple Alarm is a low cost printed circuit module
furnished with dust cover and provisions for either the alarm trip point
adjustment on the unit or it can be located remotely with a separate dial and
potentiometer. The input can be from any type thermocouple and the output is a 5
amp 120 VAC relay. Thermocouple burnout protection and automatic cold junction
are standard features.
The alarm unit consists of a solid state integrated circuit and transformer
isolated power supply. The alarm unit will provide contact transfer at the
terminals labeled NC, NO, and C. The connection between NC and C will provide a
normally closed contact and between NO and C will provide a normally open
contact. The dead band between drop-in and drop-out of the relay contacts is
approximately 75-100 microvolts.
The 15A-2 alarm can be used either as a non latching ( auto-reset ) type of
alarm or a latching type of alarm, which must be reset with a NO pushbutton
contact ( momentary contact ) which is connected to terminals labeled RESET (
N.O.). With the latching mode used, the alarm unit will remain in the alarm
condition even though the thermocouple temperature drops back below that set on
the alarm set point adjustment dial. A jumper must be placed between the reset
terminals, if a non latching system is desired.

Description
Of
Operation
The temperature monitor system consists of
a SMART-2 Digital
overtemp controller which has a relay
output at terminals #4 and #5
located on the rear of the
controller. This contact closes in an
over-temperature
condition which applies 120VAC to the 120VAC
coil of the
output relay, thus transferring the output relay contacts
to
a alarm condition.
If any one of the 3 temperature controllers
are in an alarm condition,
the output relay will be
placed in an alarm condition
and the alarm light for that particular point
will be lit.
