Using multiple Electro-Sentry 1’s in the same
application
7) Multiple Electro-Sentry 1’s can be connected together to the
same external Green/Yellow/Red Lightstack status indicator
to monitor a larger overall system, as follows:
Connect all of the individual ES1’s Green-Lightstack-
Relays in series with each other and with the external
Lightstack.
Connect all of the individual ES1’s Yellow-Lightstack-
Relays in parallel with each other and with the external
Lightstack.
Connect all of the individual ES1’s Red-Lightstack-
Relays in parallel with each other and with the external
Lightstack.
With multiple Electro-Sentry 1’s connected together as
described, the following alarm behavior is seen:
The external Green Lightstack is lit if-and-only-if all
ES1’s have no alarms present.
The external Green Lightstack is unlit if any ES1 has
any alarm present.
The external Yellow Lightstack is lit if any ES1 has a
‘Yellow_Alarm’ present.
The external Yellow Lightstack is unlit if-and-only-if all
ES1’s have no ‘Yellow_Alarms’ present.
The external Red Lightstack is lit if any ES1 has a ‘Red_
Alarm’ present.
The external Red Lightstack is unlit if-and-only-if all
ES1’s have no ‘Red_Alarms’ present.
Built-in Test Features Section:
Temperature Rise and Speed Drop Alarm Test Features
1) Press and hold the ‘TEST_LEFT_SIDE’ button on the
Front-Panel to artificially increase the temperature readings
in the left side column of temperature displays. Keep the
button pressed-in to increase the temperatures to levels
above the
Var12
_Warning_Setpt_Temperature, the
Var13
_
Shutdown_Setpt_Temperature, and/or the individual BIAS_
Temperature_Setpts. (This test can also be accessed by TB31
pins 3-4). This test can be used to test the effectiveness of
how the temperature alarm output relays will work with the
overall application. Give a manual ‘Silence_Horn/Alarm_
RESET’ command to the ES1 to ‘clear’ any alarms generated
by this test. (See Operations Notes Section “How to Clear
Alarms” for details).
CAUTION: This test will cause actual system alarms
.
2) Press and hold the ‘TEST_RIGHT_SIDE’ button on the
Front-Panel to artificially increase the temperature readings
in the right side column of temperature displays. Keep
the button pressed-in to increase the temperatures to levels
above the
Var12
_Warning_Setpt_Temperature, the
Var13
_
Shutdown_Setpt_Temperature, and/or the individual BIAS_
Temperature_Setpts. (This test can also be accessed by TB31
pins 5-6). This test can be used to test the effectiveness of
how the temperature alarm output relays will work with the
overall application. Give a manual ‘Silence_Horn/Alarm_
RESET’ command to the ES1 to ‘clear’ any alarms generated
by this test. (See Operations Notes Section “How to Clear
Alarms” for details).
CAUTION: This test will cause actual system alarms
.
Note: Concerning the TEST_LEFT_SIDE and TEST_
RIGHT_SIDE temperature tests, only one of these
tests can be performed at a time. If both of these
temperature tests are attempted at the same time, then
the test feature is disabled, and the dual activation
is actually an “Alarm_RESET” command. (See the
Operation Notes “How to Clear Alarms” for details).
3) Press and hold the ‘TEST_SPEED’ button on the Front-Panel
to artificially decrease the Speed Display value. Keep the
button pressed-in to decrease the speed to levels below the
Var04
_Slowdown_Setpt and the
Var06
_Shutdown_Setpt.
(This test can also be accessed by TB31 pins 7-8). This test
can be used to test the effectiveness of how the speed alarm
output relays will work with the overall application. Give a
manual ‘Silence_Horn/Alarm_RESET’ command to ‘clear’
any alarms generated by this test. (See Operations Notes
Section “How to Clear Alarms” for details).
Note: For the ‘TEST_SPEED’ button feature to work, the
following requirements must first be met:
•
Var09
must be set for Speed Monitoring Enabled.
• An Hour_and_Speed_Enable command must be
present at
TB34
.
CAUTION: This test will cause actual system alarms
.
