ORP CONFIGURATION

QUICK STARTUP (ORP) CONFIGURING THE CONTROLLER

The Model 54e pH/ORP controller comes pre-pro- grammed by the factory as a pH controller. In order to perform a quick startup as an ORP controller, the controller must first be switched to the pre-configured ORP program. Most ORP sensors will look and con- nect very much like pH sensors, but will have a metal ring electrode over a glass shaft with a thick end instead of a thin pH glass membrane.

To switch to an ORP controller and perform a quick startup:

1.Connect the ORP sensor to the controller. Wire to controller per Figure 2-5 or 2-6.

2.Apply primary power (Figure 2-4) to the con- troller.

3.Change the controller to ORP operation. Refer to Section 5.3, or:

A.Press any key to display the main menu.

B.Move cursor until Program is highlighted.

C.Press Enter (F4).

D.Highlight "Configure" and press Enter (F4).

E.Highlight "Display" and press Edit (F4).

F.Use the arrow key to change "Measure" from pH to ORP and press Save (F4). Warning screen appears - press Cont (F3).

4.Complete the ORP standardize instructions).

5.Preset alarm and output settings are listed below: If these values are unacceptable, refer to Section A.1 for a detailed configuration proce- dure. For a summary of the complete factory set- tings see Table A-1.

Alarm 1	(low alarm):		-1400mV
Alarm 2	(high alarm):		+1400mV
Alarm 3	(high alarm):		+1400mV
Output 1		(4mA setpoint):	-1400mV
Output 1		(20mA setpoint):	+1400mV

Configuration of the ORP settings can be done at any time after the controller has been set to ORP mode (step 3 in Quick Startup on the left). Procedures for these operations follow the ORP Standardization instructions in this appendix.

Before attempting any changes refer to the configu- ration setup list shown in Table A-1. This table pres- ents a brief description and the configurable items. The factory setting is also given with a space for the user setting. It is recommended that the list be care- fully reviewed before any changes are made.

On initial configuration, it is recommended that the settings be entered in the order shown on the work- sheet. This will reduce the chance of accidentally omitting a needed setting.
