Chapter 3 Programming
Press for 5 seconds and release to enter the setup menu.
Press and release to select the desired parameter. The display
indicates the parameter symbol. Press or to view or
adjust the value of the selected parameter.
3–1 Lockout
There are four security levels that can be selected using the
LOCK parameter.
If NONE is selected for LOCK, then no parameter is locked.
If SET is selected for LOCK, then all setup data are locked.
If USER is selected for LOCK, then all setup data as well as
user data (refer to section 1-5) except the set point are
locked to prevent them from being changed.
If ALL is selected for LOCK, then all parameters are locked to
prevent them from being changed.
How to use Conversion Curve for
Process Value:
If 4–20mA is selected for INPT, SL specifies the input signal low
(i.e., 4mA), SH specifies the input signal high (i.e., 20mA), S
specifies the current input signal value, and the conversion curve
of the process value is shown as follows:
3–2 Signal Input
INPT: Selects the sensor type or signal type for signal input.
Range: (thermocouple) Type J, K, T, E, B, R, S, N, L
(RTD) PT.DN, PT.JS
(Linear) 4–20 mA, 0–20 mA, 0–60 mA, 0–1V,
0–5V, 1–5V, 0–10V
UNIT: Selects the process unit
Range: °C, °F, PU (process unit). If the unit is set for
neither °C nor °F, then it defaults to PU.
DP: Selects the resolution of process value.
Range: (For T/C and RTD) NO.DP, 1-DP
(For linear) NO.DP, 1-DP, 2-DP, 3-DP
INLO: Selects the low scale value for the linear type input.
INHI: Selects the high scale value for the linear type input.
3–3 Control Outputs
There are four kinds of control modes that can be configured as shown in table 3.1.
SL = Setpoint Low Limit SH = Setpoint High Limit
