Setup Parameters
When you are at the top of the menu, the Series 942 displays the user level of
operation in the Upper display, and the LOC parameter in the Lower display.
When you press the MODE key, the
value
of the next parameter appears in the
Upper display, and the parameter appears in the Lower display.
Lock:
Selects the level of operator lockout.
Range:
0 - 3
Default:
0
LOC 0: All operating parameters may be viewed or changed.
LOC 1: Locks out the PID parameters. Set point, process value and events are the
only visible operating parameters, set point
is
adjustable in this level. A
profile can be viewed, changed, run or halted.
LOC 2: Locks out the PID parameters and the Program menu. Set point, process
value and events are the only visible operating parameters, set point
is
adjustable. A profile can be run or halted but
not
viewed or changed.
LOC 3: Locks out the entire Operating and Program menus. Set point and process
value are the only visible operating parameters, set point
is
not
adjustable.
A profile can be run or halted but not viewed or changed.
Input:
Selects the sensor input type. Only those input types which are compatible
with your unit will appear. See the model number information for your type.
Chang-
ing this parameter erases all profile steps and defaults them to an End step.
Range:
J, K (appears as H), t, n, c, r, S, b, Pt2, rtd1, rtd.1, 0-5, 420
Default:
J
or
r
Decimal:
Selects the location of the decimal point for all process related data. This
parameter only appears if the In parameter is 0-5 or 420.
Range:
0, 0.0, 0.00
Default:
0
Celsius _ Fahrenheit:
Selects the units of temperature measurement for the
control. This parameter only appears if In = T/C or RTD input.
Changing this
parameter erases all profile steps and defaults them to an End step.
Range:
C or F
Default:
F
Range Low:
Selects the low end of the set point range. See the model number
and specification information in the Appendix, and Table 1 on Page 26 for sensor
range values. Also used to set the low end of the process input and/or the low end
of the range for the retransmit output. 0.0VDC and 4mA represent Range Low (rL)
for process inputs and outputs. Process inputs and outputs are linearly scaled
between rL and rH.
Changing this parameter erases all profile steps and
defaults them to an End step.
Range:
Sensor range low to rH
Default:
Low limit of sensor type
Range High:
Selects the high end of the set point range. See the model number
and specification information in the Appendix, and Table 1 on Page 26 for your
sensor range values. Also used to set the high end of the process input and/or the
high end of the range for the retransmit output. 5.0VDC and 20mA represent Range
High (rH) for process inputs and outputs. Process inputs and outputs are linearly
scaled between rL and rH.
Changing this parameter erases all profile steps and
defaults them to an End step.
Range:
Sensor range high to rL
Default:
High limit of sensor type
