NOTE:
CAUTION:
FAQ’s (FREQUENTLY ASKED QUESTIONS):
Q.6:I want to switch OFF the output of Astro for a particular time
interval without affecting the main program. Which feature
should I use?
A.6:You can use ‘OFF-Hours’ feature to switch OFF the output for
a particular time period. To set OFF Hour feature, select‘OTH’
menu and then select ‘OFHR’.
Q.2:What is Manual switching (override)? When do we use it?
A.2:When it is desired to switch ON/OFF the output before the
actual event i.e. (ON/OFF event), manual override can be used.
Press the MAN key for 3 s to toggle between ON A uto & Auto
mode when relay (output) is OFF and to toggle between Auto OFF
or Auto mode when the output is ON.
Q.3:What should I do to reset all settings and Clock?
A.3:Press the Reset (RST) key. All settings will set to default
and the clock will be reset to 00:00 & the date will be set to
01/01/2000.
Q.4:How should I change clock format from 12 h to 24 h?
A.4:Press ‘ ’ & ‘MAN’ key to switch from 12 h to 24 h clock
format and vice versa.
Q.5:How does ON AUTO and AUTO OFF feature help?
A.5:ON AUTO / AUTO OFF feature is used to immediately switch
the output ON / OFF respectively, overriding the current output
condition. If the output ON time is 6:15 p.m. & we w ant to switch
ON the output earlier, at 5:30 p.m. then set the mode as ‘ON
Auto’. The output will be switched ON immediately. The mode will
automatically change to ‘Auto’ at 6:15 p.m. which is the next auto
event. Similarly the output can be switched OFF earlier than the
output OFF time using the Auto OFF feature.
Q.1:In the event of power failure, do I lose all settings in the
device?
A.1:No, the battery has a power reserve of approx 6 years at
operating temperature range. In the absence of mains supply,
we can program the device as per the requirement. However,
during power failure, the relay or LED will not operate but the
relay status can be observed on the screen.
Q.7:How can I switch the output ‘ON’ 30 min after sunset?
A.7:Use the Offset feature to change the ON time or OFF time of
the output. To set offset, select ‘OUT’ menu and then select
‘OFSR’ to set offset for rise & ‘OFSS’ to set offset for set. To switch
ON the output 30 min after sunset, set ‘OFSS’ as ‘POS’ (positive)
and enter the time as 30 min.
Q.8:I'm using Astro for my company's street lights and I want
these lights to be switched OFF from Saturday ev ening to
Monday morning. Which feature should I use?
A.8:You can use the Weekly-OFF feature for this purpose. To use
this feature, select ‘OTH’ menu and then select ‘WOFF’. Then
select ‘SA’ as the start day. Enter the start time in hours and
minutes. Similarly, enter ‘MO’ as the end day and time in hours
and minutes. If you have selected same day & time for start as
well as end, then ‘WOFF’ is not applicable.
1. Always follow instructions stated in this manual.
2. Before installation ensure that the specifications agree with
the intended application.
3. Installation should be done by skilled electrician only.
4. Inductive loads should be equipped with interference
supressors like varistors, RC snubbers.
5. Use of contactors is recommended if load exceeds the
contact rating.
1. If DST is applicable in your region, first set the DST and
then set the clock.
2. Due to properties of some lamps, it might take a few
minutes for the lamps to illuminate completely even after
the output has been switched ON.
3. Product innovation being a continuous process, we reserve
the right to alter specifications without prior notice.

BASIC FEATURES:
Offset:
Offset is used to switch ON the output before or after the
sunset or switch OFF the output before or after sunrise. This
can be achieved through the ‘oFSr’ (Offset Rise) and ‘oFSS’
(Offset Set) parameters in the OUT menu. The range for the
Offset is +/- 00 to 99 minutes.
Trigger Modes:
The output can be programmed to switch OFF/ON either at
sunrise/sunset or at twilight rise/set. If the trigger mode
‘Twilight’ in the ‘OUT’ menu is set as ‘Yes’, then the output will
be switched OFF/ON at twilight rise/twilight set. If it is set as
‘No’, then the output will be switched OFF/ON at
Sunrise/Sunset.
Day-light Saving Time (DST):
ASTRO provides settings to easily define the DST start and end
period time to effectively manage the shifting of clock, year
after year without any manual intervention.
Weekly OFF:
The Weekly Off feature is used to switch OFF the output during
Weekend's or Weekly Off days. This feature allows to define
the Weekly OFF days including the start and end time.
OFF-Hours:
The OFF-Hours feature is used to switch OFF the output for a
particular time period on a daily basis.
For e.g. If the Off Hours programmed are from 23:00 to 02:00,
then the output will be switched OFF for these 3 hours
everyday.
