N1
Running Time Meter, Door mount
N2
Operation Counter, Door Mount
P1
Time Delay Source 2 Start. Adjustable 0-10 seconds.
Standard setting is 3 seconds. Adjust via SET menu
(see page 18)
P2
Time Delay S2 Start. Adjustable 1/6 to 300 seconds.
Q2
Remote Peak Shave or Area Protection Circuit. Energize Q2
to simulate Source 1 Line failure causing the Generator to
start and transfer the load to Source 2. Should Emergency
fail during this operation, Transfer Switch will retransfer
back to Source 1.
Q3
Remote inhibit transfer to Source 2 circuit. Energize Q3
input to allow transfer to Source 2. To enable Q3 option,
engage Q3 jumper.
Q7
Inhibit transfer to Source 1 circuit. Energize Q7 input
to prevent transfer to Source 1.
R1-1/R1-3
Source 1 Over Voltage sensing for single and three
phase systems.
Source 1 Over Voltage “Fail”
Factory Default: 110%
This adjustment determines the maximum acceptable
over voltage. Adjust via the SET menu. Range is 105%
to 110% in 1% increments (see page 18). Once exceeded,
the P timer begins timing to signal the Generator to start.
Source 1 Over Voltage “Restore”
Factory Default: 105%
This adjustment determines the minimum acceptable
over Voltage threshold at which the Transfer Switch is
allowed to automatically transfer to Source 1. Adjust via
SET menu. Range is 103% to 108% in 1% increments.
“Restore” must be a minimum of 2% below “Fail” setting
(see page 18).
R15/R15D
Load Shed
Should Source 2 become overloaded, a signal can be
given to switch to the dead or Mid position.
R16
Phase Rotation Sensing
Can be turned on or off via CFG menu (see page 17).
Factory Default is on.
This feature prevents Line Source to Line Source transfers
from occurring between dissimilar phase sequences. This
condition is primarily caused by an installation error.
Connections from Source 1 and Source 2 need be verified,
compared, and corrected to remedy the inconsistent phase
rotation between the sources. WARNING: Turning off
this feature can cause severe damage to loads.
R26
Interruptable Power Rate Provisions. Allow transfer out
of Source 1 position to Source 2 or dead Source 2. Alarm
and Pre-Signal circuit included.
