9.MENU DETAIL

9.1Relay Control (Sp1-Sp4)

While in menu, all other operations are suspended.

The H340 has four setpoint parameters and up to four relays associated with those four setpoints. The setpoint LEDs on the display will light even if no relay is present for that setpoint.

To change the setpoint value, enter the menu by pressing W. If the password

allows relay control, it will be the first menu to appear. The display will show the word “Sp1”. If this is the setpoint to be edited, press RESETENTER , otherwise press T to move to the next choice. When editing Sp1, the display will alternate be-

tween Val-1 and a value. The “value” represents a threshold above or below the setpoint being set to alarm.

NOTE: Before editing this value, be sure that the decimal point is in the proper position. It is also recommended that any scaling or linearization be entered before setpoints are determined.

Press RESETENTER to choose Val-1 as the setting to be edited. Notice that the far right digit has an alternating cursor. To change this digit, use Sor T. To move to the

next digit, press W. When all changes to the value are complete, press RESETENTER to confirm the change and save it to memory.

NOTE: Any power loss before confirming a change will lose the edited value. The menu will revert back to alternating between Val-1 and value. Press T to move to the response setting.

9.1.1Response

The display will now show “Rsp.” To edit response, press , otherwise press T to move to the next choice. When editing Rsp., the display will show Hyst, Dlay, or Ltch Flashing. Use S or T to choose the required response.

Press to confirm the choice. When choosing Hyst, the display will alternate between Hyst and the current value.

To edit the value, press RESETENTER . Otherwise press T to move to the next choice. Hysteresis will be used above and below the setpoint in equal amounts. The

value represents a percentage of the setpoint. For example: If the setpoint is set to 100.00 with a high alarm and therhysteresis is set for 8.5%, the alarm will not turn on until the reading on the display reaches 108.50. Once tripped, the alarm will not turn off until the display reaches 91.50.

9.1.2Delay

When choosing Dlay, the display will alternate between Dlay and current value. To edit the value press RESETENTER . Otherwise press q to move to the next choice. Dlay will be used above and below the setpoint in equal amounts. The value

represents the amount of delay in seconds. For example, if the setpoint is again configured for high alarm and Dlay is set for 2.5 seconds the display crosses the setpoint value and a timer begins to count off the 2.5 seconds before the alarm trips. If, during those 2.5 seconds the value falls below the setpoint, no action will be taken. When the unit successfully counts off 2.5

3.2Engineering Label Placement

If the engineering unit label needs replacing, place the tip of a ballpoint pen into the small hole at the base of the engineering label in the bezel. Slide the label up until it pops out. Grasp and remove. Slide the new label half the dis- tance in, then use the ballpoint pen to slide it down into place.
