Service Manual. Contact the Sensidyne Service Department to arrange for a Returned Material
Authorization (RMA).
ONLY use genuine SENSIDYNE®replacement parts when performing any maintenance procedures
provided in this manual. Failure to do so may seriously impair instrument performance.Repair or
alteration of the product beyond the scope of these maintenance instructions, or by anyone other
than a certified SENSIDYNE®serviceman, could cause the product to fail to perform as designed and
persons who rely on this product for their safety could sustain severe personal injury or death.
AC (Earth) ground MUST terminate on each controller’s ground terminal to prevent an electric
shock-hazard. A PCB board mounted ground lug is supplied with each unit.
Operation of the alarm relays above their contact ratings may result in false alarms or relay failure.
CAUTIONARY NOTE
The output signal to the recorder, or other data gathering device, is always “live.” That is, the display
reading is transmitted directly through the recorder output to whatever peripheral device is attached
to the controller. Any recorder or other data gathering device should be turned off during
calibration.

1.1 OVERVIEW
IMPORTANT
Youmustreadthismanualinits entiretytoensureproper
operation of the controller.
This manual provides specific information concerning
the installation, operation, and maintenance of the
Sensidyne SensAlert Controller.
The SensAlert Controller, when used with a Sensidyne
external I.S. barrier (PNº 7013263), is designed to oper-
ate an intrinsically safe SensAlert transmitter in areas
classified Class I, Division 1, Groups A, B, C, D; Class II,
Division 1, Groups E, F, G.
SECTION ONE
INTRODUCTION
The Sensidyne SensAlert Controller is an integral part
of the SensAlert Gas Monitoring System. The SensAlert
Controller, housed in a NEMA 4X enclosure, provides
separate single pole double throw (SPDT) relays for
each alarm condition, plus one common relay for a
fault condition. It also serves as an interface when an
event needs to be relayed to a peripheral device, such
as a building fire alarm system. The SensAlert Control-
ler displays can display gas levels in either ppm, %vol,
or %LEL, depending on the installed sensor.
The power supply for the controller has been designed
to operate at 90-265 VAC, with the capability of add-
ing a 24 Vdc backup power supply.
Some of the features of SensAlert Four Channel Con-
troller include:
• Auto-recognition of sensors
• Lo, Hi, HiHi, & Fault alarms
• User-selectable alarm levels
• Three relay contacts per sensor
• Lockout/tagout designed case
• RS-485 serial output
• 4-20 mA / 1-5 volt output
• Password protection

1.2 COMPONENTS
1.2.1 Controller Housing
The NEMA 4X enclosure is made of high-grade, fiber-
glass reinforced polyester resin matting. The enclosure
provides a weather-resistant and water-resistant barrier
between the internal electronics and the ambient envi-
ronment. The controller cover is secured to the hous-
ing with 2 quick release latches. Each latch has a
small circular knockout that allows the case to be
locked or tagged to prevent unauthorized entry.
The Reset switch is located on the bottom of the con-
troller housing (refer to Figure 2.1). The switch can be
used to (1) unlatch a latched alarm, (2) silence a local
Lo Alarm, or (3) enter Calibration Mode (when
pressed for 5 seconds).
The Alarm Buzzer is located on the bottom of the
controller housing, next to the cable glands. The
alarm buzzer is used for the Local Alarm.
1.2.2 Display PCB
The Display PCB contains the large, 3-digit LED dis-
plays, the LCD displays, and the operator buttons that
control the menu system. The Display PCB connects
to the Bottom PCB via a 20-pin flex cable. The com-
ponents on the Display PCB are described as follows.
• Liquid Crystal Display
The Liquid Crystal Display (LCD) is a 16 character, 2-
line display located behind the front cover of the con-
troller enclosure (see Figure 1.1). During normal op-
eration, the display shows the gas name and gas con-
centration (in ppm, %LEL, or %vol) for the sensor in-
stalled at the transmitter. The display is also used for
viewing and changing various features of the
controller (e.g., alarm settings, passwords, etc.).
During alarm and fault conditions, the display shows
status messages on Line 2 describing the nature of the
condition (e.g., Lo Alarm, Missing Sensor, etc).
• Operator Buttons
The 5 Operator Buttons a control the menu system.
The menu system allows you to view and change
alarm settings, change system features, and perform
diagnostics. A detailed description of the menu system
and operator buttons can be found in Sections 1.3 &
1.4.
1.2.3 Bottom PCB
The Bottom PCB (see Figure 2.1) is attached to the in-
side bottom of the controller housing. The compo-
nents located on the Bottom PCB are described be-
low.
The Bottom PCB is populated with 11 terminal blocks.
Each terminal block consists of a base block and a
keyed, removable terminal plug that facilitates wiring.
Terminal wiring designations are described in Section
Two.
The Bottom PCB also contains jumpers, AC & DC
fuses, and a current limiting 4 channel power supply.
