DESCRIPTION

This bulletin serves as a guide for the installation, configuration and operation of LDP6-CDS Setpoint cards. The setpoint cards are available as dual relay, quad relay, quad sourcing transistor, or quad sinking transistor outputs. Only one setpoint card can be installed at a time.

The meter can be fitted with up to three option cards. The slot bays of the option cards are dedicated to a particular card function. The option card functions are: serial communications, analog output and setpoint output. Only one card from each function category can be installed.

INSTALLING AN OPTION CARD

Caution: The option and main circuit cards contain static sensitive components. Before handling the cards, discharge static charges from your body by touching a grounded bare metal object. Ideally, handle the cards at a static controlled clean workstation. Also, only handle the cards by the edges. Dirt, oil or other contaminants that may contact the cards can adversely affect circuit operation.

Warning: Exposed line voltage exists on the circuit boards.

Remove all power to the meter AND load circuits before accessing the unit.

1. Remove the main assembly from the rear of the case. Squeeze the finger holds on the rear cover, or use a small screwdriver to depress the side latches to release it from the case. It is not necessary to separate the rear cover from the main circuit card.

2. Locate the option card connector for the type of option card to be installed. Hold the unit by the rear connector, not the display board, when installing an option card.

3. Install the option card by aligning the option card connector with the slot in the rear cover. The cards are keyed by position with different main board connector locations. Be sure the connector is fully engaged and the tab on the option card rests in the alignment slot on the display board.

4. Slide the assembly back into the case. Be sure the rear cover latches fully into the case.

5. Apply the option card label to the bottom side of the meter. Do not cover

the vents on the top surface of the meter. The surface of the case must be clean for the label to adhere properly. Apply the label to the area designated by the large case label.

It is not possible to configure setpoint 1 as deviation or band actions. It is possible to use setpoint 1 for an absolute action, while its value is being used for deviation or band.

** The lower Totalizer action allows setpoints to function off of the lower 5 digits of the Totalizer. The upper Totalizer action allows setpoints to function off of the upper 4 digits of the Totalizer. To obtain absolute low alarms for the Totalizer, program the logic as reverse.

SETPOINT VALUE

-19999 to

99999

Enter desired setpoint alarm value. These setpoint values can also be entered in the Display Mode during Program Lockout when the setpoint is programmed as in Parameter

Module 3. When a setpoint is programmed as deviation or band acting, the associated output tracks as it is changed.

The value entered is the offset, or difference from .

HYSTERESIS VALUE

« 1 to

65000

Enter desired hysteresis value. See Setpoint Alarm Figures for visual explanation of how setpoint alarm actions (balance and unbalance) are affected by the hysteresis. When the setpoint is a control output, usually balance hysteresis is used. For alarm applications, usually unbalanced hysteresis is used. For unbalanced hysteresis modes, the hysteresis functions on the low side for high acting setpoints and functions on the high side for low acting setpoints.

Note: Hysteresis eliminates output chatter at the switch point, while time delay can be used to prevent false triggering during process transient events.

RESET ACTION

«

Auto LAtC1 LAtC2

Enter the reset action of the alarm output.

= Automatic action; This action allows the alarm output to automatically reset off at the trigger points per the

Setpoint Action shown in Setpoint Alarm Figures. The “on” alarm may be manually reset (off) immediately by a front panel function key or user input.The alarm remains reset off until the trigger point is crossed again.

= Latch with immediate reset action; This action latches the alarm output on at the trigger point per the

Setpoint Action shown in Setpoint Alarm Figures. Latch means that the alarm output can only be turned off by front panel function key or user input manual reset, serial reset command or meter power cycle. When the user input or function key is activated (momentary or maintained), the corresponding “on” alarm output is reset immediately and remains off until the trigger point is crossed again.

(Previously latched alarms will be off if power up Display

Value is lower than setpoint value.)

= Latch with delay reset action; This action latches the alarm output on at the trigger point per the Setpoint

Action shown in Setpoint Alarm Figures. Latch means that the alarm output can only be turned off by front panel function key or user input manual reset, serial reset command or meter power cycle. When the user input or function key is activated (momentary or maintained), the meter delays the event until the corresponding “on” alarm output crosses the trigger off point. (Previously latched alarms are off if power up Display Value is lower than setpoint value. During a power cycle, the meter erases a previous Latch 2 reset if it is not activated at power up.)

STANDBY OPERATION

« no YES

When , the alarm is disabled (after a power up) until the trigger point is crossed. Once the alarm is on, the alarm operates normally per the Setpoint Action and Reset Mode.

SETPOINT ANNUNCIATORS

The mode disables display setpoint annunciators. The mode displays the corresponding setpoint annunciators of “on” alarm outputs. The mode displays the corresponding setpoint annunciators of “off” alarms outputs. The mode flashes the corresponding setpoint annunciators of “on” alarm outputs.

PROBE BURN-OUT ACTION (DP63500 ONLY)

«

ON OFF

Enter the probe burn-out action. In the event of a temperature probe failure, the alarm output can be programmed to go on or off.

Setpoint Alarm Reset Actions

Alternate Setpoints

An Alternate list of setpoint values can be stored and recalled as needed. The

Alternate list allows an additional set of setpoint values. (The setpoint numbers nor rear terminal numbers will change in the Alternate list.) The Alternate list can only be activated through a function key or user input programmed for in Module 2. When the Alternate list is selected, the Main list is stored and becomes inactive. When changing between Main and Alternate, the alarm state of Auto Reset Action alarms will always follow their new value. Latched “on” alarms will always stay latched during the transition and can only be reset with a user input or function key. Only during the function key or user input transition does the display indicate which list is being used.
