Signal color change delay 

The signal color change delay be adjusted between approximately 1 and 127 seconds. 
This delay time affects the transition from yellow to green. If flashing yellow is enabled 
then the yellow to flashing yellow and flashing yellow to green transitions will have the 
same delay. The delay time is adjusted using a flat blade screwdriver inserted into the 
“pot” labeled “DELAY” on the circuit board. If you rotate it fully to the left you’ll get 
the minimum time delay. Rotating it fully to the right will give you the maximum time 
delay.  Set  the  delay  based  on  your  own  personal  preference.  On  smaller  layouts  you 
may  wish  to  have  a  shorter  delay  so  that  a  looping  train  does  not  run  into  a  red  or 
yellow  signal  it  just  caused  itself!  You  can  change  the  delay  time  as  you  wish  even 
when the power to the 

Block Animator

/2 is on.

Visual Effects (Flashing Yellow, Signal Fade) 

The 

Block Animator

/2 introduces Flashing Yellow and Signal Fade effects.  

 
 

Flashing  Yellow

  adds  another 

indication, Approach Medium, to the 
signal  sequencing.  When  enabled 
(switch  #9  in  the  ON/CLOSED 
position)  the  signals  will  sequence 
from red 

 yellow 

flashing yellow 

 green.  

 

 

 

Signal Fade 

reproduces the behavior 

of older prototype signals which used 
bulbs. As the indications change the 
aspects (colors) will fade off and on. 
To enable this feature switch #10 must 
be in the ON/CLOSED position. 

        

 

 
 

Power 

The 

Block Animator/2

 accepts AC or DC power (7 - 16V). Power consumption, including the signals, ranges from ~60 mA 

(photocell version) to ~225 mA (infrared version). If you are only using a single board then you can use the AC terminals to 
provide power as shown in Figure 15a. You can use the accessory terminals on your throttle/power pack. If you are using 
more than one 

Block Animator/2

 (for example, if you’re interlocking with turnout positions) then you should consider 

powering them all from a single 

DC

 source as shown in Figure 15b. Watch the polarity and make sure you know what is 

positive! Contact us if you are uncertain! 

When power is first applied the signal outputs will turn on briefly in sequence (Red 

 Yellow 

 Green).

Other Applications 

We have an instruction supplement and application notes on our website which cover topics such as interlocking a signal (i.e. 
force it to red) with the position of a turnout or controlling multi-headed signals.
