Package
| Type: | 1/18 DIN extruded aluminum housing with sheilded front panel switch assembly. |
Programmable Functions
| Program: | Sequences through the following program options. StPt (Setpoint Control Voltage) SPH1 (Alarm Setpoint High #1) SPL1 (Alarm Setpoint Low #1) SPH2 (Alarm Setpoint High #2) SPL2 ( Alarm Setpoint Low #2) HH (Hysteresis for High Alarm Setpoints) HL (Hysteresis for Low Alarm Setpoints) CAL (Full Scale Flow Calibration Value) dP (Decimal Point location) |
| StPt: | Flowmeter Control Voltage (0-5 vdc) can be set using the front panel Program switches. Setpoint voltage is automatically calculated using the programmed setpoint value (StPt) and the programmed full scale (CAL) value. Flowmeter output offset voltage is automatically compensated for whenever a ZERO function is activated. |
| Alarms: | (2) high and (2) low digital alarms are set via the front panel switches and activated whenever the alarm setpoints are exceeded. The appropriate front panel alarm annunciator will illuminate and open collector transistors will activate when the alarm setpoints are exceeded. |
| HH & HL: | (1) high and (1) low hysteresis value can be programmed providing up to 99 counts of digital alarm deadband. |
| Cal: | Full Scale Calibration value used during calibration. |
| dP: | x.xxxx,xx.xxx,xxx.xx and xxxx.x decimal point locations can be set using the Program switches. |
| Calibration: | Allows ZERO and CAL (Full Scale Calibration) functions. |
| Zero: | ZERO switch and rear panel D-Sub connector control line (low) activates display zeroing function over the full display range. |
| Cal: | CAL switch allows push button full scale calibration to CAL value. |
