Explanation of Commonly Used Menu Entries
Reference # & Menu Item Function
9) Aux In This indicates the measured voltage from the analog input set point
control. This will reflect the voltage received at the TIM-100/120 from
the equipment (5000 = 5.000 V).
10) Pres Sp1 For pressure exhaust controllers, this entry allows the pressure set
point to be reviewed or edited. For the SENTRY 1000, 2000 = 2.000”

O. For the SENTRY 1510, 2540 = 25.40 mm H

O.
14) Flow Sp1 For flow exhaust controllers, this entry allows the flow set point to be
reviewed or edited.
34) Pres FS For pressure exhaust controllers, this indicates the full pressure scale
for the exhaust control device. The full scale must match the
pressure transducer inside the control device.
35) Flow FS For flow exhaust controllers, this indicates the full flow scale achiev-
able by the control device.
37) Aux FS This indicates the full scale of the analog signal input. When using a
0-5 V control signal (analog interface), this item must be set to 5000,
representing 5.000 V full scale.
38) SaveData This is used to save the TIM-100/120 configuration to nonvolatile
memory. Refer to section 2, page for instructions on saving
parameter changes.
39) BaudRate This is used to set the RS422/RS485 serial port speed rate. The
process equipment controller or host computer must use the same
baud rate. The TIM-100/120 can handle up to 9600 baud.
40) Parity This item allows the selection of the following serial data parity: Odd,
Even, One, and Zero. After changing parity, Save Data must be
executed first and then power to the TIM-100/120 must be cycled
once (On to Off to On).
51) GainFine This indicates the gain (proportional) coefficient that is used in the
PID loop This indicates the same value as the “Gain” menu item but
allows the operator a finer increment of adjustment.
55) Deadband This indicates the band on either side of the set point, within which
the process variable can move and not cause control loop action.
68) StptMode This is used to define where the controller receives its set point. The
selections are single, analog, dual and quad. Single indicates a
single digital set point from an RS422/RS485 serial connection or
manually set by the user. This set point is the value under Pres Sp1.
Analog indicates a remote set point, through a 0-5 V analog interface
.
Dual and Quad are not used.
69) OperMode This indicates the process parameter to be controlled. Pressure is
indicated by Pres, flow is indicated by Flow.
