setting
after the set number of attempts are completed.
N.O. (normally open) potential free contact of
both the relays are provided for customer's usage.
Number
of starting attempts are set for 3 as standard
but can be provided anywhere form 1 to 15. This
is only factory set and therefore has to be specified
at the time of order.
LLOP
and DYNAMO Interlocking are provided as per following
details.
------------------------------------------------------------------------------------------------------------------------------------------------------
LLOP INTERLOCKING
Attempt relay will
get on only when the low lubricating oil pressure
(LLOP) signal (either-ve at terminal 7 or +ve
at terminal 8 of the unit) is available and LLOP's
LED will glow.
DYNAMO INTERLOCKING
Attempt
relay will get on only when the D+signal (at terminal
3 of the unit) from the Dynamo terminal is-ve.
This signal is -ve when engine speed is below
set value and the corresponding LED will glow
accordingly.
Both the above mentioned interlocking can be by
passed by conncting the corresponding terminals
with the desired signals permanently and their
corresponding LED's would glow.
MODEL AER-DT
Adjustable
Delay Time (upto 30 mins) for Engine Start is
provided in this model. The unit would start the
attempt relay only after the delay time is over.
Delay time can be bypassed by connecting +ve supply
to terminal 6 of the unit. Therefore by providing
a switch for +ve supply at terminal 6, the unit
can be converted to either instantaneous of delay
start.
SETTING/REPEAT ACCURACY
± 2%
of the set time.
OPERATING VOLTAGE
12 VDC or 24 VDC
or any other voltage including A.C. on special
requirement (+25% to -35% of supply voltage variation
is acceptable)
RELAY
CONTACT RATING
6Amps resistive
load or 2 Amps inductive load at 230 VAC or 24
VDC.
INSULATION
The unit will withstand
2.5% KV 50Hz for one minute between all external
A.C. supply and relay contact terminals connected
together and body.
