2100UM22.DOC Model: 2100 &2300 Series 1.0 INSTRUMENT OVERVIEW 1.1 FEATURES 1.2 Rev: 2.
Model: 2100 &2300 Series 2100UM22.DOC Rev: 2.2 OPERATION The unit senses level using a RF Capacitance measurement technique for very high-resolution measurements. A probe mounted in a vessel forms a capacitor with the vessel wall (or with a concentric shield around the probe for non metallic vessels). The capacitance of this arrangement is directly proportional to the level of material in the tank and may be measured to provide signals and controls.
Model: 2100 &2300 Series 2.0 2100UM22.DOC Rev: 2.2 INSTALLATION NOTE: If any damage to the instrument is found, please notify an Arjay Engineering representative as soon as possible prior to installation. 2.1 PROBES Capacitance probes may be selected from a variety of styles for use with liquids, liquid interfaces, and granular materials. The probe length is customer specified for the height of material desired to be measured. Usually Teflon coated probes are used. 2.

The current state is displayed on the right extreme of the bottom line of the LCD. A Disable setting will disable Alarm relay alarms even if an Alarm condition exists. The factory default setting is ON (ENA) which allows Alarm relays activation. Relays can be enabled AFTER calibration and setup are complete.
Model: 2100 &2300 Series 2100UM22.DOC Rev: 2.2 above the High Setpoint. No action is taken when the process level is between the High and Low Setpoints. In the alarm condition, the corresponding alarm LED is turned ON, and the relay is energized. Low Yes Alarm condition set and reset as above. In the alarm condition, the corresponding alarm LED is turned ON, but the relay is de-energized. The Relay Settings menu is now displayed from which other relays may be selected to be set up.

2100UM22.DOC Model: 2100 &2300 Series 4.0 Rev: 2.2 OPERATION IN THE FOLLOWING TEXT A MENU WILL BE DISPLAYED AS A PATH. FOR EXAMPLE THE AUTOCAL MENU: [CALIB\ 1]. (CALIB key then 1 for AUTOCAL). SETTINGS MENU: [SETUP\3] (SETUP key then 3 for SETTINGS). The 2000 Level Monitor uses a high precision and highly repeatable RF technique to measure capacitance, which in turn is used to calculate level.
00UM22.DOC Model: 2100 &2300 Series 4.2 CALIBRATION Rev: 2.2 [CALIB] The unit may be calibrated 3 different ways: Automatic Calibration and 2 Manual Calibrations. Pressing the CALIBRATION key enters the CALIBRATION menu: *** CALIBRATION **** 1-Auto 2-Manual 3-Slope/Off 4-FS val 4.2.1 AUTOMATIC CALIBRATION [CALIB\1] This is typically done for a new installation.
Model: 2100 &2300 Series 4.2.3 SLOPE AND OFFSET 2100UM22.DOC Rev: 2.2 [CALIB\3] Use this feature to view and or modify the SLOPE and OFFSET calibration values directly. Press the CALIBRATION key to enter the CALIBRATION menu then 3 for Slope/Off. Enter the desired SLOPE and OFFSET. If no change is desired just press the Enter key in each case or a Menu key to go to another menu such as the DISPLAY menu. 4.2.
2100UM22.DOC Model: 2100 &2300 Series Rev: 2.2 for the appropriate relay indicates the alarm condition. The relay is de-energized (with no delay) when the level falls below the low control point. Selecting low action will energize the relay when the level falls below the low control point for at least the time delay period. The relay is deenergized (with no delay) when the level rises above the high control point. 4. FAILSAFE.
Model: 2100 &2300 Series 2100UM22.DOC Rev: 2.2 Conditions 1, 3, 5, 7 are typically for control applications where the positive action i.e. turning on a pump, should be shut off during a power failure to the Arjay level controller. Conditions 2, 4, 6, 8 are typically for alarm applications where the positive action i.e. sounding an alarm if the level is at a high level, should also be in place during a power failure to the Arjay level controller. 4.3.
Model: 2100 &2300 Series 2100UM22.DOC Rev: 2.2 Since the pump should be turned off if the Arjay unit fails or in the event of a power failure i.e. the positive action state is not the same as the failure state, the failsafe setting should be No. Since the positive action is desired when the level drops below the low control point, the relay setting should be Low Acting. Since the pump starter requires power to turn on the pump, the normally open contacts should be used.
2100UM22.DOC Model: 2100 &2300 Series 4.4 SETUP MENU Rev: 2.2 [SETUP] The SETUP menu is used for one-time setup and for Diagnostics. ********SETUP******** 1-PMC 2000 2-Diags 3-Settings 4.4.1 PMC 2000 (Manual) [SETUP \ 1 \ 2] This menu is to calibrate the 2000 series controller for the particular PMC-2000 level transmitter module located at the probe head.
