2-7 Adjustment of balancing relay (SBR-10)
After setting dial gauge, limit switch, resistance, and then adjust SBR-10.
Put selector switch of local box into remote position.
push SW3 (Auto Scan) button switch for 3-4 seconds.
In this time, the auto lamp flickers and operates to set the output value (4-20mA DC ).
And the operating takes around 120-180seconds. (while the operating, do not operate
arbitrary)
If the auto lamp flickers rapidly and
actuator stops working, Please check
whether resistance signal or resistance
using angle is normal or not.
(When the dial gauge is 50%, you can
see
red
point
on
the
resistance(potentiometer))
When the operating is completed, press
the SW3 (Auto scan) button switch for
3~4seconds to complete the operation
A fault lamp flickers when the input
signal
is
blocked
or
when
the
po,-) of the input signal changes
or when the resistance is out of
output(100~900
Ω)
In normal case, you can adjust the balancing relay as above.
But if the installation site is deviated from the actuator, you can fine-tune it as shown below
