The same pair of wires is used to both transmit and receive data.
4.6 REAL-TIME CLOCK WIRING (PTC901) Time synchronization between multiple PTC901 meters can be accomplished through a hardware interface on the Real-Time Clock option card. This RS485 type interface allows connection of up to 32 PTC901 meters in a two-wire multidrop network, at distances up to 4000 ft. In a synchronization network, one PTC901 meter is programmed as the Host, while all other meters are programmed as Slaves.
6.0 PROGRAMMING THE METER OVERVIEW PROGRAMMING MENU DISPLAY MODE The meter normally operates in the Display Mode. In this mode, the meter displays can be viewed consecutively by pressing the DSP key. The annunciators to the left of the display indicate which display is currently shown; Timer (TMR), Cycle Counter (CNT), or Date (DAT). The Time Display for the Real-Time Clock is shown with no annunciator. Any of these displays can be locked from view through programming. (See Module 3.
6.1 MODULE 1 - TIMER INPUT PARAMETERS ( ) PARAMETER MENU Module 1 is the programming module for the Timer Input Parameters. In the Display Mode, the TMR annunciator indicates the Timer display is currently being shown. An EXCHANGE PARAMETER LISTS feature, which includes the Timer Start and Timer Stop Values, is explained in Module 2.
FLASH TIMER ANNUNCIATOR TIMER RESET AT POWER-UP « « ª ª The Timer can be programmed to Reset at each meter power-up. This parameter allows the Timer annunciator (TMR) to flash when the Timer is running or stopped/inhibited. Select if a flashing indicator is not desired. TIMER INPUT STATE AT POWER-UP « ª Determines the “Run/Stop” State of the Timer at Power-up. This parameter does not apply to timer input operation.
DISPLAY SELECT (Level Active) DISPLAY HOLD (Level Active) « « « ª ª When active (maintained action), the meter continuously scrolls through all displays that are not “locked-out” in the Display mode. (See Module 3 for Display Lock-out details.) A sub-menu provides Scrolling Speed selection. When active (maintained action), the meter “freezes” the display values entered as in the sublist, while normal meter operation continues internally. Program only one user input for this function.
CHANGE DISPLAY INTENSITY LEVEL « OUTPUT SET (Level Active) « ª « « ª ª ª When activated (maintained action), the meter continually activates the output for all Setpoints entered as in the sublist. When activated (momentary action), the display intensity changes to the next intensity level (of 4). The four levels correspond to Display Intensity Level ( ) settings of 0, 3, 8 & 15.
6.3 MODULE 3 - DISPLAY AND PROGRAM PARAMETERS LOCK-OUT ( ) PARAMETER MENU ** These parameters only appear if a Setpoint option card is installed. = Setpoint Number 1 thru 4 Module 3 is the programming module for setting the Display Lock-out Parameters and the “Quick Programming Mode” Value Access Parameters. In the Quick Programming mode, after the PROGRAM LOCKOUT PARAMETERS and before the Security Code ( ), a Display Intensity Level ( ) parameter is available when the security code is non-zero.
6.4 MODULE 4 - CYCLE COUNTER PARAMETERS ( ) PARAMETER MENU Module 4 is the programming module for the Cycle Counter Parameters. In the Display Mode, the CNT annunciator indicates the Cycle Counter display is currently being shown. An EXCHANGE PARAMETER LISTS feature, which includes the Cycle Counter Start and Stop Values, is explained in Module 2. CYCLE COUNTER START VALUE « ª CYCLE COUNTER COUNT SOURCE to 999 The Cycle Counter returns to this value whenever a Cycle Counter Reset occurs.
Timing Diagrams for Predefined Timer Operating Modes NOTE: Input A is shown as a Sourcing input (active high). If a Sinking input (active low) is used, the logic levels for Input A would be inverted. On-Delay / Interval Timing On-Delay Timing Input A Input A T Output 1 T T1 Output 1 Off-Delay Timing T2 T Interval Timing (Level triggered) Input A Input A T T Output 1 T T Output 1 The input signal must be wired to both the Input A and User Input 1 terminals.
6.6 MODULE 6 - SETPOINT (ALARM) PARAMETERS ( ) This module can only be accessed if a Setpoint Card is installed. PARAMETER MENU = Setpoint Number 1 thru 4 Module 6 is the programming module for the Setpoint (Alarm) Output Parameters. This programming module can only be accessed if a Setpoint card is installed. Depending on the card installed, there will be two or four Setpoint outputs available.
TIME-OUT VALUE « TIMER STOP « to ª ª The Time-Out Value only appears when the Setpoint Action ( ) is programmed for Timed Output mode ( ). In this mode, the Time-Out Value is the Setpoint Output time duration, from activation to deactivation. This value is always entered in minutes, seconds, and hundredths of seconds format. The maximum Time-Out Value is 99 minutes 59.99 seconds.
6.7 MODULE 7 - SERIAL COMMUNICATIONS PARAMETERS ( ) This module can only be accessed if a Serial Communications Card is installed. PARAMETER MENU * Only appears if the Real-Time Clock Card is installed. Module 7 is the programming module for the Serial Communications Parameters. These parameters are used to match the serial settings of the meter with those of the host computer or other serial device, such as a terminal or printer.
SENDING SERIAL COMMANDS AND DATA Command String Examples: When sending commands to the meter, a string containing at least one command character must be constructed. A command string consists of a command character, a value identifier, numerical data (if writing data to the meter) followed by the command terminator character * or $. 1. Address = 17, Write 350 to Setpoint 1 String: N17VE350$ 2. Address = 5, Cycle Counter value, response time of 50 to 100 msec. min.
Abbreviated Transmission ( = ) BYTE DESCRIPTION 1-12 13 14 15 16 17 12 byte data field, 6 bytes for number, up to 3 bytes for decimal points. (Carriage return) (Line feed) Auto/Manual Mode Register (MMR) ID: U This register sets the controlling mode for the outputs. In Auto Mode (0) the meter controls the setpoint output. In Manual Mode (1) the outputs are defined by the registers SOR.
COMMUNICATION FORMAT Data is transferred from the meter through a serial communication channel. In serial communications, the voltage is switched between a high and low level at a predetermined rate (baud rate) using ASCII encoding. The receiving device reads the voltage levels at the same intervals and then translates the switched levels back to a character. The voltage level conventions depend on the interface standard. The table lists the voltage levels for each standard.
TIME DISPLAY FORMAT « ª 12-59p 12-59 To calibrate the RTC, install the meter in its normal operating environment, and set the time based on a known accurate reference (such as the WWV broadcast or the Atomic Clock reference which is available via the internet). After 30 days of normal operation, compare the RTC time to the reference, and note the amount of time gained or lost. Refer to the tables on the next page for the proper Offset value to enter, given the amount of time drift observed.
6.9 MODULE 9 - FACTORY SERVICE OPERATIONS ( ) PARAMETER MENU DISPLAY INTENSITY LEVEL E -&7 « ª RESTORE FACTORY DEFAULTS Enter the desired Display Intensity Level (0-15) by using the arrow keys. The display will actively dim or brighten as the levels are changed. This parameter also appears in Quick Programming Mode when enabled. Use the RST and/or arrow keys to display and press PAR.
