SAFETY ALERTS - SAFETY SIGNAL WORD DEFINITIONS
This document contains safety alert pictorial Symbols and Words that point out areas and procedures that require
special attention with regards to safety. These Symbols and Words are defined in ANSI Z535.4-1998, Product Safety
Signs and Labels.
DANGER:
DANGER indicates an imminently hazardous situation which, if not avoided, will result in death or serious injury.
WARNING:
WARNING indicates a potentially hazardous situation which, if not avoided, will result in death or serious injury.
CAUTION:
CAUTION indicates an imminently hazardous situation which, if not avoided, may result in minor or moderate injury.
It may also be used to alert against unsafe practices.
The safety alert pictorial symbol appears in this document to make users aware of important operating and
safety concerns.
Tools and Test Equipment Required
•
Miscellaneous hand tools
•
DMM (digital voltmeter)
Voltage Selection
1.
If you have a 208, 220 or 240 V ATS the voltage range can be changed. The factory setting is either set to HIGH
(220 to 240 V) or LOW (208 V) depending on ATS model ordered. If the factory preset is not desired, performing
the following steps will change the voltage transfer points.
2.
Make sure both Primary and Backup AC sources to the ATS are de-energized.
3.
Remove the ATS case cover.
4.
Locate the jumper at JP1 (HIGH) or JP2 (LOW). See figure 1.
5.
To change the voltage selection simply move the Jumper from the JP1 (HIGH) to JP2 (LOW) position or JP2 (LOW)
to JP1 (HIGH) position (depending on the factory preset of your ATS).
6.
Replace the ATS case cover.
Remote Status / Alarm Monitoring
1.
A DB-9 female connector in the rear of the unit provides status / alarm signals for remote monitoring of the sta-
tus of the ATS.
2.
Primary AC Input Status DB-9 Pins are:
_5_
NO
_1_
NC
_2_
COM
3.
Backup AC Input Status DB-9 Pins are:
_6_
NO
_3_
NC
_4_
COM
4.
When Primary AC Input is present and IN SPECIFICATION, there is an OPEN circuit between pin
_5_
and pin_
2_
.
When Primary AC input is OUT OF SPECIFICATION, there is a CLOSED circuit between pin_
5_
and pin_
2_
.
5.
When Backup AC Input is present and IN SPECIFICATION, there is an OPEN circuit between pin
_6_
and pin
_4_
.
When Backup AC input is OUT OF SPECIFICATION, there is a CLOSED circuit between pin_
6_
and pin_
4_
.
6.
Maximum voltage and current that can be used for monitoring the status and alarm of the ATS Series is 120 VDC
(VAC), 1 A (maximum DB-9 connector rating).
