Product Description 1.1
1.1.1 GENERAL
This instrument is a microprocessor based single loop controller capable of
measuring, displaying and controlling temperature, pressure, flow, and level
from a variety of inputs. Most outputs are easily tuned using the instrument
Pre-Tune and Auto-Tune functions.
Control functions, alarm settings and other parameters are easily entered
through the front keypad. E

Technology (100 year life) protects against
data loss during AC power outages.
The input is user configurable to directly connect to either thermocouple,
RTD, mVDC, VDC or mADC inputs. The instrument can operate from a
90-264 VAC, 50/60 HZ power supply, or optional 24V AC/DC power supply.
1.1.2 DISPLAYS
Each instrument is provided with dual displays and status indicators as
shown in Figure 1-1. The upper display displays the value of the process
variable. The lower display displays the setpoint value. Status indication is
as shown, see Figure 1-1, page 6.
1.1.3 CONTROL
The instrument can be programmed for on-off, time proportioning, or cur-
rent proportioning control implementations depending on the model num-
ber. A second control output is an available option. Proportional control
implementations are provided with fully programmable PID parameters.
1.1.4 ALARMS
Alarm indication is standard on all instruments. Up to two alarm outputs
are possible. Alarm type may be set as Process Direct or Reverse (high or
low), Deviation Direct or Reverse (above or below setpoint), Deviation
Band Type (closed or open within band), or Loop Reverse or Direct. Alarm
status is indicated by LED.
