LEDs are used in a recognizable line configuration

for continuous monitoring of switch position.  A new
LCD display shows source availability, exercise time
delay operation and system source condition.  A new
simplified adjustment is featured for voltage, frequency
and time delay settings.

The control operates off a close differential 3

phase under-voltage sensing of source 1, factory
standard setting 90% pickup, 80% dropout; under-
frequency sensing of source 1 factory setting 95%
pickup; voltage and frequency sensing of source 2,
factory standard setting 90% pickup voltage, 95%
pickup frequency. All factory settings are operator
adjustable (see table below).

A test is standard (fast test/load/no load) to

simulate source 1 failure - automatically bypassed
should source 2 fail.

• Available in ALL transfer modes:

~ Open, Delayed & Bypass
~ Closed (with newly integrated transition control)

• User-friendly programmable engine exerciser, 

used for the engine generator with or without 

load, at ANY interval in a one-year period

• Operating voltages available in a single 

controller for most domestic and international 

applications

• Real-time display of ATS status, including  

active timer(s)

• Multiple levels of user-defined password 

protection

• Serial communications allowing connectivity 

with other ATS's, paralleling switchgear, and 

SCADA systems

• Time-tested synchronous logic automatically     

measures phase angle and frequency allowing 

disturbance-free transfer 

• Unsurpassed statistical ATS/System monitoring

available in real-time

• T3/W3 elevator pre-signal. Automatically 

bypassed if the selected source fails, minimizing

time an elevator is without power

• Universal Motor Disconnect (UMD) sends 

a pre-signal, post-signal or both to any motor 

control center. Not bypassed in an outage, 

the UMD ensures safety in the event of a 

single phase loss

• Voltage unbalance detection standard

• Extensive 2/5/10 Warranty

• UL, CSA and IEC listed

(CISPR 11) (Exceeds EN55011 & MILSTD 461 Class 3)

• ESD Immunity test per EN61000-4-2 (Level 4)
• Radiated RF, electromagnetic field immunity test

per EN61000-4-3 (ENV50140) 10v/m

• Electrical fast transient/burst immunity test

for EN61000-4-4

• Surge immunity test per EN61000-4-5 IEEE C62.41 

(1.2 x 50ms, 5 & 8 kV)

• Conducted immunity test per EN61000-4-6 (ENV50141)
• Voltage dips and interruption immunity EN61000-4-11

• Separate line voltage components for controller isolation 
• Inputs optoisolated for high electrical immunity to transients and noise
