Introduction to this Manual

What is in this

manual?

This installation and operation manual provides detailed technical information about the

PM500 Programmable Process Ratemeter. It should serve as your technical resource to

install, set up, operate, and test the PM500.

Who should

use this manual

(audience)

Keep in mind that the function of the PM500 installed in a mechanical process is to monitor

position, capacity, speed, etc; therefore, it must be installed by qualified personnel only. This

manual is designed for persons who have the primary responsibility to install, set up, operate,

and test the PM500.

The secondary audience would be those persons seeking technical information about the

electrical concepts and operation of the PM500.

Knowledge

level

Persons installing, setting up, and operating the PM500 should have good knowledge and

understanding of electrical and mechanical concepts and principles pertaining to

Programmable Process Ratemeters. Again, the PM500 should be installed by qualified

personnel only.

Introduction to this Product

The PM500 is a stand-alone display device that accepts up to two 4–20 mA DC analog input signals.

 The display has four 7-segment LED digits with decimal points.

 The PM500 can be programmed to display any value of user units from ’00.00’ to ‘9999’ and from ‘-0.00 to -

999’.

 The PM500 has either two SPDT relay outputs or four SPDT with programmable functions (UNUSED,

UNDER and OVER).

 The PM500 has an option for 2 16 bit 4 to 20 mA output signals, which are isolated from the 4 to 20 mA input

signals.

 The PM500 display has 5 status LED’s so you can determine which input you are viewing, as well as for

indicating when the PM500 is in the programming, or diagnostics modes. It also signals the user when there is a

sensor failure.

 The PM500 has 2 regulated +24 VDC outputs that can each supply 50 mA maximum. (This supply can be used

to power sensors, etc.).

The User Interface

The user interface consists of a keypad, the four character display, five discrete LEDs, several user variables, and

three menus—the user variable menu, the security menu, and the diagnostic menu. The three menus are each accessed

by a menu key; the VAR key accesses the user variable menu, the DECIMAL POINT key accesses the security menu,

and the DIAG key accesses the diagnostic menu. In each of these menus there is an intermediate level (level 2)

enabling you to select a menu item and a final level (level 3) enabling you to change or edit the selected menu item.

The method for selecting which menu item to edit depends on what menu you are in. In the VAR menu use the up,

down, left, and right arrow keys to edit the two digits of the user variable number. In the security menu and in the

DIAG menu use the up and down arrow keys to scroll through menu item prompts.

Once a menu item has been chosen, press the ENTER key to move to the final level (level 3) to edit the variable value

or perform the diagnostic action.

To edit a user variable value, use the left and right arrow keys to move the cursor (the flashing digit) to the digit

whose value you want to change, then use the up and down arrow keys to change the value of the digit. Press the

ENTER key to accept the value or press the ‘abort’ key to throw away the changes that you have made. (The ‘abort’

key depends on which menu you are in, i.e. the VAR key enters the user variable menu and the VAR key aborts the

user variable menu.)

For example, to change a user variable value, press the VAR key to go to level 2—select user variable number. While

in level 2, edit the display so that it shows the user variable number whose value that you want to change. Then, press

the ENTER key to accept the user variable number and go to level 3—change user variable value. While in level 3,

edit the display so that it shows the new user variable value. Then, press the ENTER key to accept that value and

return to level 1—the user units display level. When the user accepts a value the PM500 will test it and will not allow

an out-of-range or illegal value. If at any time you don’t like the changes that you have made while you are in a

particular level, press the abort key to discard the changes and go back to level 1—the user units display level.

The SECR menu works in a similar way to allow you to change the security variable values. The diagnostic menu will

allow you to perform a diagnostic test, to perform calibration actions, or to observe the state of the system, thereby

enabling you to set up your system or to troubleshoot your system installation.

The five front panel LEDs are used to indicate which menu you are in or to indicate status information about the

PM500. There are five LEDs: Sensor Error, PROG, INPUT A, INPUT B, and KEY ERR. When a menu key is

pressed the LED associated with that menu turns on to indicate which menu you are in.

Table 1; Associations Between Keys, LEDs, and Menus

The Input “A” LED is associated with input channel A. The Input “B” LED is associated with input channel B.

The Input LED that is illuminated shows the user which input channel is being displayed.l

The KEY ERR LED is used to indicate an invalid key press, an invalid user variable number, or an invalid user

variable value. It shuts off after a timeout period of 500 ms.

The PROG LED is ‘OFF’ when the display is showing a real-time value selected by the display function variable.

(SECR Menu) The Security Variables

The SECURITY menu is accessed by pressing the DECIMAL POINT key.

In the security menu the user has access to three variables. The input password variable (PIn), the password definition

variable (PdEF), and the security definition variable (SdEF).

The security features defined by the security definition variable ‘SdEF’ are enabled anytime the input password ‘PIn’

is different from the password definition ‘PdEF’.

In other words, in order to access locked-out functions the user has to enter an input password that matches the

password definition (PIn = PdEF).

In order to lock out unauthorized changes to user variables the user must enter a password definition that is unknown

to unauthorized users (PIn ≠ PdEF). Any attempt to access the password definition by an unauthorized user will result

in a display of “HIdn” (hidden).

The following table indicates how menu access is controlled by the digits of the security definition variable.
