MODEL100 - 12/24Volt
GENCLOCK
By Flight Systems Inc.
User Manual
Installation
Mounting
The GENCLOCK requires a minimum 2.5” long piece of 35mm x 7.5mm DIN rail to mount to.
Power
The clock power supply requires a supply current of 1/2 AMP MIN and a supply voltage of 10V AC/DC MIN
and 35V AC/DC MAX. Power is applied to terminals “1” and “2” with no concerns for polarity. NOTE: make
sure all hardwired battery chargers are disabled before removing or disconnecting batteries. Failure to
do so can produce a high voltage spike on the positive battery bus, that that will damage the clock!
Output
The output from the clock is taken from terminals “3” (common), “4” (normally open), and “5” (normally closed).
These are dry contacts that are rated for 10 amps at 250V.
Battery Backup
The control uses a CR2032 battery to keep time and exercise settings during brief power failures. The amount
of time that the backup battery will power the clock varies. During such an event, the display and output will be
disabled to conserve power, but the clock will continue to keep time. If the unit is going to be disabled for an
extended period of time, remove the battery cover and pull out the battery.
Initially the battery or battery cover is not installed. Install the included battery into the top of the clock, in the
slot provided. Then, snap in the battery cover. If you want to test the condition of the battery, check the voltage
from the top of the battery holder to the small pad marked “GND” on the base circuit board. You should see
3.2V to 2.6VDC, any lower and you should replace the battery.
NOTE: If you notice the clock losing time or booting up in programming mode after a brief loss of power, the
battery is weak and should be replaced.
Programming Mode
On initial power up the control will boot up in programming mode. Before the clock will become active, you will
have to adjust your desired settings and advance until you get to the normal display screen. Programming
mode can also be achieved by using the RESET option (press and hold the STEP and ENT buttons while in
the normal display screen). While in programming mode, the clock stops, and the output is disabled. You can
use this feature as an Emergency Stop. Leaving the clock in the programming mode will disable the clock and
it will not become active until you have advanced to the normal operating screen.
1. Set 12/24hr configuration
On initial power up, or using RESET, the clock will ask you to set the time configuration for 12 or 24HR. Use
the DWN/UP buttons to change and then press ENT to accept and advance to next screen.
2. Set hours
The next screen that will appear will ask you to set the current hour. Again, use the DWN/UP buttons to reach
desired hour and press ENT to accept and advance to the next screen.
