About This Manual
This manual is intended for those responsible for programming a computer or tool to operate with
the SENTRY process exhaust control system through the use of serial communications.
Complete instructions for installing and operating a SENTRY system may be found in the
controller's installation and operation manual (i.e. SENTRY 1000, SENTRY 1510, etc.).
This manual describes the following:
• Physical Installation (TIM-100/120/200 Only)
• Commonly Used Command Menu Parameters
• Operation in Manual, Analog and Serial Communication Modes
• Required Programming for Using Serial Communication
Description
The SENTRY TIM-100/120 is a microprocessor-based interface used in conjunction with many of
Progressive Technologies Inc. process exhaust controllers. The SENTRY TIM-100/120 allows
the user to communicate electronically with the process exhaust controller (such as the SENTRY
1000) for changing the set point and reading actual process exhaust values. It can be configured
at the PTI factory to be used with controllers that maintain constant pressure or constant flow.
The TIM-100/120 can be operated in stand-alone mode (manual mode), with a 0-5 Volt process
tool interfaced analog signal (analog mode) or with process equipment/facility computer interfaced
serial communications (serial mode).
Two primary configurations of the TIM-100/120 are offered: 1) TIM-100 with a graphics LCD and
keypad and 2) TIM-120 which supports the analog interface and serial communications without
the LCD and keypad interface.
TIM-100
Note:
• The TIM-120 is pre-configured for the accompanying SENTRY system. However, a Program
Module is required if access to the command menu is required.

  • Page 9: Section 3: Command Menu

    Section 3: Command Menu 3.1 The Command Menu The SENTRY TIM-100/120 is common to all PTI automated exhaust controllers. As such, the TIM-100/120 contains a number of command items that may not be applicable to the specific SENTRY system being installed. The complete menu is listed below. The menu contains 71 individual entries, 64 of which are directly accessible by the keyboard using the arrow keys.
  • Page 10 3.1 Command Menu 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).
  • Page 11 All the controllers used in conjunction with the TIM- 100/120 have a patented PTI piston regulator. The piston regulator compensates for fluctuations in facility exhaust to maintain a regulated process exhaust. The highly responsive nature of the SENTRY controller off loads the PID algorithm such that the algorithm is only required to change the controller set point.
