Overview The D-Series operator interface (sold separately) provides users with the ability to locally monitor and modify operating parameters of the D-Series controller to which it is attached. This is accomplished through the 4 x 20 character back-lit LCD and the four membrane front panel push buttons provided.
Monitor Mode At power up, the D-Series controller flashes its firmware version momentarily and then enters monitor mode. In monitor mode, the controller sequentially cycles through its eight control loops (channels), displaying key parameters of each. Figure 1.0 below illustrates the channel parameters displayed in monitor mode, as well as definitions of the four front panel push buttons. Channel Indicator

General Programming Procedure The flow chart below details the general procedure for programming the D-Series controller via the local operator interface. This process of involves the following steps: 1. Enter program mode 2. Select the desired control loop channel 3. Selected the desired process loop parameter 4. Adjust the selected parameter to the desired value 5. Exit program mode (return to monitor mode)

SETPOINT Programming The Setpoint control parameter determines the temperature above or below which a channels cooling and heating relays are engaged. In COOL mode setpoint determines the temperature above which cooling is engaged. In HEAT mode, setpoint determines the temperature below which heating is engaged. In AUTO mode, setpoint determines the temperature around which both cooling and heating is engaged.

MODE Programming Each D-Series channel supports the following thermostatic modes: § § § §
COOL Mode: In this mode the channel will engage its cooling relay whenever its probe temperature rises above its setpoint value. HEAT Mode: In this mode the channel will engage its heating relay whenever its probe temperature falls below its setpoint. AUTO Mode: In this mode the channel will automatically switch between HEAT mode and COOL mode as needed to maintain temperature around its setpoint. OFF: In this mode all thermostatic operation and alarm processing is disabled for the selected channel. Additionally, when networked to TankNET® control software, data logging and alarm notifications for the channel are also disabled.

DEVIATION ALARM Programming The deviation alarm parameter (SPDEV ALRM) specifies the maximum desired temperature deviation from setpoint for alarming purpose. Should the channel’s probe temperature exceed these thresholds, an alarm condition is raised and indicated by the front panel ALARM LED. Additionally, when networked to TankNET control software, D-Series channel alarms may also trigger e-mail alarm notifications. Note: To disable alarm processing, set ALDEV ALRM equal to 0.0° Example: For: SP = 20.0°C, SPDEV ALRM = 2.0°C; A channel alarm state will exist per the following: 18.0°C > Probe_Temp > 22.0°C

1. Press and hold for 2 seconds to enter program mode
2. Press as needed to select desired channel
3. Press as needed to advance to the SPDEV ALRM parameter
4. Press as needed to adjust SPDEV ALRM to the desired value (0.0 for OFF)
5. Press and hold for 2 seconds to end program mode and return to monitor mode or press the advance button again as needed to select another parameter

DIFFERENTIAL Programming Channel differential determines the amount of hysteresis applied to thermostat switching near setpoint. Access to this parameter requires an extra programming step. Differential is applied per the following: §

COOL Mode: COOLING ON: Probe_Temp >= SP + Differential COOLING OFF: Probe_Temp <= SP HEAT Mode: HEATING ON: Probe_Temp <= SP - Differential HEATING OFF: Probe_Temp >= SP AUTO Mode: see COOL and HEAT modes above

OFFSET Programming The offset parameter provides a means of calibrating a channel’s probe temperature to a known reference temperature. This single-point calibration procedure can be performed at any reference temperature between 0°C and 50°C with equal accuracy across the probe’s full temperature range of -25°C to +105°C. Offset is algebraically added to its probe temperature to produce a calibrated temperature reading, which is then used for all thermostat logic and alarm processing. Access to this parameter requires an extra programming step.
