GENERAL DESCRIPTION The Apollo Intelligent Thermistor Meter (IMY) accepts standard Thermistor inputs and precisely linearizes them into temperature readings. Like an RTD, a thermistor is a temperature sensitive resistor, but the thermistor provides a much larger resistance change per degree. Since thermistors provide a large resistance change, sign[...]

PROGRAMMING AND OPERA TING THE IMY PROGRAMMING THE IMY Although the unit has been programmed at the factory, the set-ups will generally have to be changed to suit the application. Basic set-up is complete after selection of the temperature units, decimal point placement, and selection of the digital filtering level. Before actually trying to progra[...]

DISPLAY RESULT OF “P” BUTTON “Pro” <> “0” - Causes the indicator to return to normal display mode. Any changes to set-up data are permanently stored in the E 2 PROM. “Pro” <> “1” - Entry into this module allows the user to select the Thermistor type, whether the display will read in degrees Fahrenheit (F) or Celsius [...]

MODULE #4 - PROGRAM DIGIT AL FIL TER AND REMOTE INPUT PROGRAM DIGITAL FILTERING If the displayed process signal is difficult to read due to small process variations or noise, increased levels of filtering will help to stabilize the display. This programming step may be used in conjunction with display rounding programming ( P r o1&2 ) to help m[...]

PROGRAM FUNCTION OF E1-CON AND OPTIONAL E2-CON (Cont’d) “9” - If the alarm option is installed, a low level resets a latched or unlatched alarm into its inactive state. This provides manual override of alarms for system start-up and other unusual events such as system testing. “10” - A negative going edge toggles the display between “in[...]

MODULE #5 - PROGRAM INTEGRA TOR/TOT ALIZER Programming for the integrator/totalizer consists of four programming steps: totalizer decimal point position, time base, scale factor and low temperature disable. Note that the decimal point position of the integrator/totalizer can be set independent of the decimal point position of the input. The totaliz[...]

MODULE #6 - PROGRAM ALARM/SETPOINT If the alarm option is installed, this module is used to configure the operation of the alarms to a variety of combinations. The programmable options are HI/LO acting, auto/manual reset (latching) , tracking, assignment to input or integrator/totalizer, display alarms, alarm values and hysteresis (deadband) values[...]

ALARM #2 ASSIGNMENT TO INPUT OR INTEGRATOR/ TOTALIZER Alarm #2 may be programmed to activate on either the input or the integrator/totalizer value. If the integrator/totalizer option is not installed, this step defaults to the input. “ASN-2” < > “INPUt”or “totAL” PROGRAM VALUE FOR ALARM #2 The range of the alarm value is -999 to 9[...]

MODULE #7 - PROGRAM SERIAL COMMUNICA TIONS Several programmable parameters must be programmed before serial communication can occur.

MODULE #9 - SERVICE OPERA TIONS The indicator has been fully calibrated at the factory. If the unit appears to be indicating incorrectly or inaccurately, refer to the troubleshooting section before attempting this procedure. When re-calibration is required (generally every 2 years) , this procedure should only be performed by qualified technicians [...]

OPERA TING THE IMY After completing all set-up operations, the unit is ready to install and operate. After power is applied, a display test consisting of illuminating all segments for 2 seconds is performed. Afterward, the input or total will appear, depending upon the display mode prior to the last power-down. To switch the display to input, press[...]

The indicator responds to a host of commands, including change a[...]

SENDING COMMANDS TO THE IMY When sending commands to the unit a command string must be constructed. The command string may consist of command codes, value identifiers, and numerical data. Below is a table outlining the codes the indicator will recognize. COMMAND FUNCTIONS T transmits the requested information specified by the identifier (A-I, K, an[...]

If illegal commands or characters are sent to the IM, an asterisk (*) must be sent to clear the input buffer. The IM will not respond to an illegal or incomplete transmission. The diagrams show the difference in the timing considerations for either Abbreviated or Full Character Transmission, or if a Reset Command is issued. Note: If Full Transmissi[...]

RECEIVING DA T A FROM THE IMY Data is transmitted from the indicator whenever a “T” or “P” command is received via serial communications or a remote input, E1-CON or optional E2-CON pin is programmed for print request, is activated. If the abbreviated transmission was programmed, just data will be transmitted with no built-in delay. (If ful[...]

SERIAL COMMUNICA TIONS EXAMPLES CONNECTING TO AN RLC PRINTER The drawing shows the indicator with the 20 mA Serial Communication Option set-up with an RLC Model DMPC printer. An external current source is required to implement the printer’s busy signal to the indicator’s receive loop, which prevents overruns. The “Print switch” is a momenta[...]
