CALIBRATION
RANGE Input
Range Minimum Span
Input 1 & Input 2
4-20 mA 0.15 mA
10 V
0.10 V
An Error message will appear if the input 1 and input 2
signals are too close together.
INPUT
IMPEDANCE Voltage ranges: greater than 1 M

Current ranges: 50 - 100

(depending on resettable fuse impedance)
INPUT
OVERLOAD Current input protected by resettable fuse, 30 VDC max.
Fuse resets automatically after fault is removed.
Relays
RATING 2 or 4 SPDT (Form C) internal and/or 4 SPST (Form A)
external; rated 3 A @ 30 VDC and 125/250 VAC resistive
load; 1/14 HP (
≈ 50 W) @ 125/250 VAC for inductive loads
NOISE
SUPPRESSION Noise suppression is recommended for each relay contact
switching inductive loads; see page 21 for details.
DEADBAND 0-100% of span, user programmable
HIGH OR LOW
ALARM User may program any alarm for high or low trip point.
Unused alarm LEDs and relays may be disabled (turn off).
RELAY
OPERATION Automatic (non-latching)
Latching (requires manual acknowledge)
Sampling (based on time)
Pump alternation control (2 to 8 relays)
Off (disable unused relays and enable Interlock feature)
Manual on/off control mode
RELAY RESET User selectable via front panel buttons or digital inputs
1. Automatic reset only (non-latching), when the input
passes the reset point.
2. Automatic + manual reset at any time (non-latching)
3. Manual reset only, at any time (latching)
4. Manual reset only after alarm condition has cleared (L)
Note: Front panel button or digital input may be assigned to
acknowledge relays programmed for manual reset.
TIME DELAY 0 to 999.9 seconds, on & off relay time delays
Programmable and independent for each relay
FAIL-SAFE
OPERATION Programmable and independent for each relay.
Note: Relay coil is energized in non-alarm condition.
In case of power failure, relay will go to alarm state.
