Setup
Setup Parameters
When you are at the top of the menu, the Series 965 displays the user level of
operation in the upper display, and the LOC parameter in the lower display.
Press the MODE key and 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 lock-out as defined below.
Range: 0 - 4
Default: 0
LOC 0: All operating parameters may be viewed or changed. Manual operation
is permitted. When in manual operation, percent power is adjustable. Bumpless
transfer to manual mode can occur on sensor break.
LOC 1: The set point, actual, and alarm settings are the only visible parameters,
set point is adjustable in this level. Manual operation and auto-tune are permit-
ted. When in manual operation, percent power is adjustable. Bumpless transfer
to manual mode can occur on sensor break.
LOC 2: The set point, actual, and alarm settings are the only visible parameters,
set point is adjustable in this level. Manual operation is permitted. When in
manual operation, percent power is adjustable. Bumpless transfer to manual
mode can occur on sensor break.
LOC 3: The set point and actual are the only visible parameters, set point is
adjustable in this level. Manual operation is not permitted. Bumpless transfer is
defeated and outputs are disabled on sensor break.
LOC 4: The set point and actual are the only visible parameters, set point is not
adjustable in this level of lock-out. Manual operation is not permitted. Bumpless
transfer is defeated and outputs are disabled on sensor break.
Input: Selects the sensor input type. The internal DIP switch must also match
the In parameter. See Figure 21 on Page 14 for DIP switch orientation, and see
Table 1 on Page 18 for input type temperature ranges.
Range: J, K (appears as H), t, n, S, rtd, rt.d, 0-5, 420 Default: J
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. Make sure the
internal DIP switch matches the In parameter.
Range: 0, 0.0, 0.00
Default: 0
Celsius _ Fahrenheit: Selects the units of temperature measurement for the
control. This parameter only appears if the In parameter is a thermocouple or
RTD input. The default is dependent on the dFL parameter located in the Cali-
bration menu. Refer to the Appendix. Range: C or F
If dFL = US: Default: F
If dFL = SI: Default: C
Range Low: Selects the low limit of the set point. Also used to set the low end
of the process input. 0.0V
Î (VDC) and 4mA represent Range Low (rL) for
process input. The process input is linearly scaled between rL and rH. See the
model number and specification in the Appendix for range values, or refer to
Table 1 on Page 18. Range: Sensor range low to rH
Default: Low limit of sensor type/-500 for process input

NOTE:
Process input does
not have sensor
break protection or
bumpless transfer.
NOTE:
Set the LOC param-
eter value as the
final step in pro-
gramming the
Series 965 control-
ler to prevent
locking yourself out
of the Operations
and Setup Menu
during initial
programming.
