3. NAMES AND FUNCTIONS OF EACH PART
/ PARAMETER
3.1 UT130 Names and Functions of Each Part
(Principles of Key Operation)
Data display (red)
• In the operating display, either PV (measured value) or
SP (target setpoint) is indicated.
Which parameter takes precedence over the other
depends on the parameter "DSP" value.
• In the parameter setting display, either the parameter
codes or parameter value is indicated.
• If an error occurs, the error code is displayed.
Alarm 1 (AL1) / Alarm 2 (AL2) lamps (red)
AL1: Lit when the alarm 1 is activated.
AL2: Lit when the alarm 2 is activated.
SP display lamp (orange)
• Lit when SP is displayed or being changed.
• Flashes slowly (approx. once every second) when
a parameter code is displayed.
• Flashes fast when a parameter value is being changed.
Output (OUT) display lamps
(Left: orange; right: green)
Lit while control output is being output.
Flashes according to the control output value during time-
proportional output. (Flashes slowly when control output
value is small; flashes fast when control output value is large.)
• The left lamp lights up in orange during control output of
standard type.
• In heating/cooling control, the left lamp lights up in orange
when the heating-side output is active; while the right lamp
lights up in green when the cooling-side output is active.
• In the operating display, it switches between the PV (measured value)
and SP (target setpoint) displays.
• Registers the data value changed using the data change keys.
• Switches between operating displays or parameter setting display
sequentially.
• Pressing the key for 3 seconds or more in the operating display
retrieves the operating parameter setting display. You can transfer to
the setup parameter setting display form the operating parameter
setting display.
• Pressing the key for 3 seconds or more in either an operating or setup
parameter setting display transfers back to the operating display.
SET /ENT key (data registering key)
Data change keys
• When PV is displayed in the operating display, a press of
the or key switches to the SP display.
• When a parameter code is displayed, pressing either key
once displays the parameter value (which can then be
changed).
• Changes SP and the parameter values.
• Pressing the key decreases the data value and
pressing the key increases it. Holding down the key
will gradually increase the speed of the change.
