ENGINE STARTUP MODE
With function switch 6 on turn on the power to the receiver to enable the Engine Startup Mode. When activated the Supervi-
sion LED will come on and bypass the Murphy switch to allow the engine to start and stay running until the transmitter has sent
its relay ON command to the receiver thus ending the bypass timer and taking control of the receiver and turning off the Super-
vision LED. If the transmitter has not sent the relay ON command within 15 min the receiver will kill the engine and you will
have to turn the receiver off and then back on again to get it into Engine Startup Mode again.
SUPERVISION FEATURE
The Supervision Feature is a great way for checking at a glance the integrity of communications between the transmitter and
receivers. The supervision feature is designed to work with only one transmitter per system as the supervision feature’s timer
can operate on multiple receivers at the same time. When function 9 (Refresh) is turned on in the transmitter, it will send out a
check-in signal
(technically it’s a command telling each receiver on the system to reset it’s supervision timer, i.e. system is
working properly
) every 45 minutes. If the check-in signal is not heard by the receiver before the internal supervision timer
expires, due to transmitter or receiver issues, the receiver will then look at its function switches (7, 8 or 9) and take the selected
course of supervision action. See below.
FAIL-SAFE OPERATION
RELAY 1 OUTPUT ONLY
This feature works with the Supervision
feature as described above but lets us
take safety a step further. Fail-Safe
mode allows the receiver to control the
#1 internal relay by activating or deacti-
vating itself if the transmitter is not
working properly.
SCENARIO 1
Turning on Function switch 7
will
make the receiver’s internal #1 relay
energize if there is a system failure
(closing N.O. to COM.).
SCENARIO 2
Turning on Function Switch 9
will
make the receiver’s internal #1 relay de-
energize if there is a system failure
(closing N.C. to COM.).
LOAD SHARING
Different delay times on the receivers
can help with large electrical current
pulls in the same field on start up.
