Understanding Rain Sensor Parameters
The rain sensor closes the curtains when rain is sensed on the sensor element. You control how much
rain shuts the curtain by the location the sensor is mounted and by adjusting the sensitivity knob
inside the rain sensor. Anytime rain is sensed the curtain will close for a maximum of approximately 3
minutes [parameter C3]. As soon as the rain is no longer sensed, the curtain will try to reopen.
Troubleshooting & Amp Overload
If your screen is flashing
E ‐ 1
thru
E ‐ 4
one of your curtains is tripped the amp overload. The amp
overload stops a motor if the amps climb to high. This curtain will not go again from temperature
until you clear it. The remaining curtains will continue working.
Even if a curtain is overloaded you can force it by using the toggle switches.
Take care when doing this.
You may be able to figure out the problem by forcing the curtain. Force it to go open. While it’s
running, watch the amp reading on the screen. If it spikes near the top, the top limit is not set
correctly.
My curtain overloads all the time. However the curtain still moves.
If a curtain overloads every couple of days or less, you may have a problem. It could be the limit
switch on the motor is not stopping the curtain until it’s wrapped too tight or a rope, strap or weeds
are wrapped in the curtain.
My curtain overloads quickly. Curtain does not move.
You curtain motor maybe bad. Also check for damaged cords around the motor.
Tech note:
The controller does not consider the motor overloaded the first time the amps spike
above the curtain’s setpoint. It will try multiple times.
It tries multiple times until it decides the motor is overloaded for real.
Default is set to try twice.
Example: If curtain tries to open, and draws too may amps then the curtain tries to open a second
time and again draws too many amps the curtain will be overloaded for Open. After a while the
curtain may try to close, if the motor can jog close, it will clear the overload. Now the curtain can go
open again.
