1.
|
These “Gadgets” are used for automatic change - over between a combination of Two machines (Air conditioners).
|
2.
|
A.T.M. Xpert-2c operates on a single phase supply source (220 VAC± 15% 50 Hz) through single stabilizer and SHELTER CARE-2b, 2c & 2d can operates either on a single phase supply source (220
VAC± 15% 50 Hz)connected across or any two separate phases are connected with L1 & L2 terminals, through separate stabilizers (2 Nos.). |
3.
|
Above models deliver two separate outputs of 220 VAC 20 Amperes to operate / drive up to said capacity machines in cyclic manner for the programmed time / period. |

Features
& Specifications |
|
1. |
Provides 2 out puts, to drive 2 ACs. |
|
2. |
Both out puts are available in CYCLIC
way, after a preset time. ( one out
put at a time) |
|
3.
|
Pre set time is selectable by Dip
switch-4. (5 Hrs. or 10
Hrs.)
Microprocessor calculates the Run
Time. If Power fails, controller
saves
the current status. |
|
4.
|
As power up the controller Relay-1 is
switched ON after the “ON DELAY”
of
3 minutes, LED-1 (yellow) blinks during
on delay time. LED-1 becomes off when
Relay-1 gets starts. |
|
5.
|
Key-1 (quick starts) is used to
by-pass ON DELAY. |
|
6.
|
After completing the 5Hrs. or 10Hrs.
run time (as selected by Dip switch
-4) Relay-1 becomes switched off, and
Relay-2 becomes ON with
15 seconds
delay, for next cycle. During this
delay LED-1 (yellow)
blinks for 15 seconds. |
|
7.
|
Key-2 (system ON/OFF) is used to switch
ON and OFF the system (keep press
for>3sec. for both logics) No out put is
available in OFF mode. |
|
8. |
LED-2 (red) glows, when system
is OFF. |
|
9.
|
Dip switch-3 is used to
select AUTO or MANUAL
function. In AUTO mode,
controller works in cyclic way
with equal time duration in both
channels. But in manual
mode, it provides
only one out put permanently
(as selected by Dip switch-3).
The single out put also
behaves in cyclic way with
un-equal time duration, 5 Hrs.
ON. & 1Hr, or
10Hrs. ON & 2Hrs. OFF in
NORMAL position. And 5
minutes ON & 1 minute OFF,
or 10 minutes On & 2
minutes OFF in DEMO.
Position. During OFF cycle,
O/P is not available, but both
LED-1 & 2 blinks alternately, in
order to represent OFF cycle. |
|
10.
|
Dip switch -2 is used to select
OUT
PUT-1 or OUT PUT-2. (This switch is
operational, when Dip switch -3 will
be in manual mode.) |
|
11.
|
Dip switch -1 is used to select
NORMAL or DEMO. function.
In normal mode, change
over time is 5Hrs. and 10Hrs.
(as selected by Dip switch -4),
in Demo mode, 5Hrs.
becomes 5 minutes and
10Hrs. become 10 minutes. |
|
|
NOTE-1:-
|
To re-set the run time
counter, keep press the
Key -1 (quick starts) for
>5sec. or until both LED
-1&2 glows for a moment
when system is ON (not in
time delay mode).Time
counter of both sections
becomes zero, and system
starts from O/P-1. |
|
NOTE-2:-
|
In manual mode only, (when
any out put is selected) and
power becomes fail during
OFF time, If OFF time was
spent >50%, controller keeps
OFF the selected O/P for
balance period after power
re-gain. If OFF time was
spent <50%, controller starts
the selected O/P from zero
time after power re-gains. |
|
NOTE-3:-
|
In manual mode only, (when
any out put is selected)
and power becomes fail
during ON time, If ON time
was spent > 75%,
controller starts the
selected O/P from zero
time after power re-gain.
If ON time was spent <75
%, controller provides
the O/P for balance
period. |

Notes/Operations |
|
1.
|
Keep T.B.R. Switch in “On” position for “Auto” (Timer) mode, and wait (Up to 3
Mins.) for output. To avoid “On delay” press “Quick Start” Key. |
|
2. |
“Line” L.E.D. glows Red when “On delay” works. |
|
3. |
“Line” L.E.D. glows Green when Timer provides output, for machines. |
|
4.
|
Keep T.B.R. switch in “Off” position, when Timer is not in use (to avoid battery discharged) OR when using machines manually. |
|
5.
|
Keep T.B.R. Switch in "OFF" Position & “Auto/M-I/M-II” Selector Switch in M-I or M-II position (as required), for Manual operation. In manual mode “on delay” will activate again, therefore, wait (Up to 3 Mins.) for
output. To avoid “On delay” press “Quick Start” Key. |
|
6.
|
Keep “Demo./4Hrs./8Hrs.” switch in Demo. Position, when testing the system. And select 4 Hrs. or 8 Hrs. (as required) after successful installation / testing. |
|
7.
|
To “Re-set” the time, switch Off T.B.R. switch once and switch On again after few seconds. The On delay will activate again therefore, wait (Up to 3 Mins.) for output. To avoid “On delay” press “Quick Start” Key. |
|
8. |
Connect Alarm wires to the potential free contacts for HRT and power fail (PF). |
|
