All information in this manual is for
reference and guidance purposes,
and does not substitute for required
professional training, conduct,

jurisdictional/professional codes and
regulations.
Non-Fulton product information is for

from the component manufacturer.

CAUTION
The minimum return water
temperature to the boiler is 140°F (60°C)
when fi ring on oil. Failure to maintain
this will void the warranty.
Unburned oil, unlike gas, does not leave
the combustion chamber during purge.
A temperature exceeding 120°F**
(48 C) in the boiler room may cause
premature failure of electrical
components. Provisions should
be made to maintain an ambient
temperature of 120°F** (48 C) or less
(the panel box interior should not
exceed 125°F** [51 C]).
**Pumps, PLC or ModSync panels may
require lower ambient temperatures or
additional cooling.
 Min. Loop Temp: Minimum setpoint temperature at which the boiler can
operate.
 Max. Loop Temp: Maximum setpoint temperature at which the boiler can
operate.
 SC-500 Setpoint: Boiler setpoint when SC-500 setpoint mode is selected.
 SET BOILER ON TEMPERATURE
1. From Main Menu screen, select System Confi g.
2. Select Sensor Confi g and set.
 SET PROPORTIONAL BAND, INTEGRAL AND DERIVATIVE VALUES
The Proportional Band, Integral, and Derivative Values are accessed via the PID
Confi guration Screen.
 Proportional Band: This is the percentage of change in proportion to the
diff erence between setpoint (SP) and process output (PV).
 Integral: The integral is a variable time period used to adjust an output.
 Derivative: This variable allows the anticipation of whether the PV will
overshoot the SP, and reduces the output as needed.
 Manual Reset: This value will off set the PID.
 Yokogawa UT 32A Basic Programming:
 CHANGE SET POINT
1. SP (set point) display reads current set point in degrees F.
2. Press the SET/ENTER button to change the set point. Use left and right
arrows to navigate to digit you wish to change. Press up/down arrow to
change digit. When complete, press SET/ENTER again to set the new value.
 SET BOILER ON/OFF TEMPERATURE
1. There are two parameters that are required to set up the hysteresis around
the set point. These parameters are HY1 and A1.
2. To access HY1: Press the DISP button until HY1 appears. (Factory default
setting is 10).
3. To navigate to A1: Press PARA for 3-5 seconds, then arrow to SP. Press SET/
ENTER. Arrow to A1. (Factory default setting is -5). Pressing DISP will return
you to front screen.
NOTE:  The following is an example. With these default settings and a set
point of 140 F, the boiler would turn on at 140F and turn off at 150F. The
negative of A1 shifts the HY1 of 10 around set point.
