DESCRIPTION AND SPECIFICATIONS
1.1 FEATURES AND APPLICATIONS
The Model 1054A Microprocessor Analyzers, with the appropriate sensors, are designed to continuously measure and control pH, ORP, conductivity, percent concentration, dissolved oxygen, or total free chlorine in industrial and municipal processes.
The Model 1054A Conductivity Analyzers are housed in a NEMA 4X (IP65) weatherproof, corrosion-resistant, flame retardant enclo­sure suitable for panel, pipe or wall mounting. All functions are accessed through the front panel membrane keyboard which fea­tures tactile feedback. Measurement data may be read at any time. However, settings may be protected against accidental or unau­thorized changes by a user selectable security code. The display indicates the measured value in engineering units as well as tem­perature, alarm status, hold output and fault conditions.
The 1054A transmits a user selected isolated current output which is continuously expandable over the measurement range for either direct or reverse action and can be displayed in milliamps or percent. Output dampening of 0-255 secs. is user selectable.
The output and relay default settings are user selectable for hold or fault mode operation. The hold output function allows manual con­trol during routine sensor maintenance.
Continuous self diagnostics alert the operator to faults due to analyzer electronics, integral RTD failures, open wiring and process variable range problems. In the event of a fault condition or hold mode diagnosed by the analyzer, the output will be set to a pre­set or last process value and the relays will be set to their default set­tings.
Dual alarms are a standard feature on the Model 1054A and are programmable for either high or low operation. Alarm 2 may be programmed as a fault alarm. Both alarms feature independent setpoints, adjustable hysteresis and time delay action. The time delay is convenient when an alarm is used for corrective action, such as shutting down a demineralizer for regeneration. Time delay will ignore a temporary breakthrough and prevent shutting down a de-mineralizer unit prematurely. A dedicated interval timer with relay is also provided.
Automatic or manual temperature compensation is keyboard selectable. The process temperature is accurately measured from an integral RTD in the sensor assembly and is read on the display. For greater accuracy, the temperature indication may be standard­ized to the process temperature. The temperature may be config­ured to read in ÞC or ÞF.
Calibration is easily accomplished by simply immersing the sen­sor in a known solution and entering the value. With a two point calibration, the Model 1054A will automatically calculate the tem­perature slope of the solution. Upon routine standardization a sen­sor cell factor value is calculated, and a trend of this value can be used to track sensor coating.
The Model 1054A Microprocessor Analyzer comes standard with an LCD display. An LED display is available as an option. An optional wall or unistrut mount enclosure is available for extra pro­tection of the analyzer in high solids or cold environments.
FM AND CSA APPROVED For Class I, Division 2, Gas Groups A, B, C, and D.
SELF DIAGNOSTICS with a user selectable fault alarm.
KEYBOARD SECURITY is user selectable.
NO BATTERY BACK-UP REQUIRED. Non-volatile EEPROM memory.
DUAL ALARMS WITH PROGRAMMABLE LOGIC. A third relay is provided with timer func­tions.

The Model 1054A Conductivity Analyzer measures over the range of 0-2 µS/cm to 0-1,000 mS/cm. Temperature slope may be adjusted any- where between 0 and 5% to provide greater accuracy in chemical concentration control. The temperature slope is factory set at 2% as a rep­resentative value, but each conductive solution has its own set of temperature vs. concentration curves. The Model 1054A C will automatical­ly calculate the temperature slope for any given solution, or permit manual adjustment of the temperature slope if already known. On calibra­tion the analyzer will also automatically correct for cell constant variations for better measurement accuracy.

1. Remove the four screws that secure the rear
cover of the enclosure.
2. (Not required for wall mounting configuration).
Remove the four screws holding the front panel assembly of the enclosure and carefully pull the front panel and connected printed circuit boards straight out.
3. Follow the procedure for the appropriate mount-
ing configuration: Section 2.3.1 for panel mount­ing, Section 2.3.2 for wall mounting, Section 2.3.3 for pipe mounting, or Section 2.3.4 for wall mount enclosure mounting.
2.3.1 Panel Mounting (Standard). The Model 1054A C is designed to fit into a DIN standard 137.9 mm X 137.9 mm (5.43 inch X 5.43 inch) panel cutout (Refer to Figures 2-1 and 2-2).
1. Prepare the analyzer as described in Section 2.3.
2. Install the mounting latches as described in
Figure 2-2 (latches are shown oversize for clarity). If the latches are not installed exactly as shown, they will not work correctly. The screws provided are self-tapping. Tap the screw the full depth of the mounting latch (refer to side view) leaving a gap greater than the thickness of the cutout panel.
3. Align the latches as shown and insert the analyz­er enclosure through the front of the panel cutout. Tighten the screws for a firm fit. To avoid damag­ing the mounting latches, do not use excessive force.
4. Replace the front panel assembly. Circuit boards must align with the slots on the inside of the enclosure. Replace the door and four front panel screws.
2.3.2 Wall Mounting Plate with Junction Box
(P/N 23054-01). Refer to Figures 2-4 and 2-5.
