    BCD input is converted to an SSI output which is then inter- preted by the PM4-SSI. The SEt OPER setup function is used to select the input type required. If the input from a general SSI output device then select SSI at this function. If the input is from model RM-BC or RM4-BC then there is a choice of either 8 bit BCD (bc 8) or 24 bit BCD (bc 24).

    Explanation of functions The PM4 setup and calibration functions are configured through a push button sequence. The three push buttons located at the rear of the instrument (also at the front on some display options) are used to alter settings. Two basic access modes are available: FUNC mode (simple push button sequence) allows access to commonly set up functions such as alarm setpoints.

  • Page 14 Alarm relay low setpoint A Lo Display: Any display value or OFF Range: Default Value: OFF Displays and sets the low setpoint value for the designated alarm relay . Note will be replaced by the relay number when displayed e.g. A1Lo for relay 1. Use this low setpoint function if a relay operation is required when the display value becomes equal to or less than the low setpoint value.

  • Page 16 low setpoint values. The trip time provides a time delay before the alarm relay will activate when an alarm condition is present. The alarm condition must be present continuously for the whole trip time period before the alarm will activate. If the input moves out of alarm condition during this period the timer will reset and the full time delay will be restored.
  • Page 17 an independent setpoint value or may be linked to operate at a fixed difference to another relay setpoint, known as trailing operation. The operation is as follows: Alarm 1 (AI) is always independent. Alarm 2 (A2) may be independent or may be linked to Alarm 1.
  • Page 18 level set by the brGt function and the display brightness set by the duLL function. The display dull level is selectable from 0 to 15, where 0 = lowest intensity and 15 = highest intensity. This function is useful in reducing glare when the display needs to be viewed in both light and dark ambient light levels.

By pressing the ^ or v pushbutton at the dCPt function the decimal point position may be set. The display will indicate as follows: 0 (no decimal point), 0.1 (1 decimal place), 0.02 (2 decimal places), 0.003 (3 decimal places) and 0.0004 for display with more than 4 digits.

Either the U.SCL or USER SCLE function must be set to on if the P.SEt operation is required.The remote input can be used to force the display to the preset value, this preset value is set at the P.SEt function. Any changes in the output from the sensor will then add or subtract from the displayed preset value.
  • Page 25 5.29 Display scaling factor SCLE Display: 1 to any display value Range: Default Value: 1 The SCLE value is used together with the INPt value to calculate the value to be displayed from the SSI input value transmitted from the encoder. These two functions are used to calculate the display value and are used only when the alternative scaling methods of U.SCL and USER SCLE are both set to OFF.

  • Page 27 The user scale function allows the front panel F button to be used to enter a scale value. To operate by this method the U.SCL function must be set to on. If this method of scaling is used the INPt and SCLE functions are not used and the USER SCLE function must be set to OFF. The remote input or P button must be used to zero the display with the encoder in its zero position or set the display to a preset value with the encoder at a known position prior to the U.SCL operation.
  • Page 28 5.36 Clear user scale operation CLr U.SCL Display: Range: Default Value: n/a The display scaling via the U.SCL function operation can be cleared at this function. Pressing the ^ and v buttons simultaneously will clear the user scaling and will cause the scaling to revert to a 1:1 equivalent i.e.
  • Page 29 2. At the CAL1 function press ^ and v simultaneously, then release them. The display will indicate the live input value. Do not be concerned at this stage if the live input display value is not what is required. 3. Press then release the F button. The display will indicate SCL1 followed by a value. Use the ^ or v button to change this value to the required display scale value at this input.

    When bc 8 or bc24 operation mode is selected the PM4-SSI must receive its SSI input from a model RM-BC or RM4-BC converter. These instruments convert a BCD input signal to SSI. The input can be selected as either parallel, strobed or addressed BCD.
  • Page 34 Select SSI if the input is an SSI signal (binary or Gray code) from encoder etc. The remaining two modes are for use only when the PM4-SSI is connected to a RM-BC or RM4-BC converter. The two remaining modes are bc8 for 8 bit BCD and bc24 for up to 24 bit BCD inputs. The BCD input can be either parallel, strobed or addressed.
