M-2603 Autodaptive Regulator Control
LED Indicators
The front panel LED indicators alert the user to the following conditions:
Out-of-Band RAISE and LOWER (3 position): GREEN (Initial Timing), AMBER (switch operation in 1 to 5
minutes), RED (switch operation in 1 minute or less).
CPU OK, flashing GREEN, indicates the control is working properly.
REV PWR, RED, indicates a reverse power condition exists.
NEUTRAL LIGHT, AMBER, indicates regulator is in the neutral position.
Output Contacts
Raise Output: Capable of switching 6 A at 120 V ac to 240 V ac motor power.
Lower Output: Capable of switching 6 A at 120 V ac or 240 V ac motor power.
Voltage Measurement Accuracy
Voltage accuracy of
K
0.7% in accordance with ANSI/IEEE C57.15-1986 defining control accuracy of
operation.
Communications
Serial communications is available via a front panel-mounted, optically-isolated RS-232 serial data port in a
DE 9-pin configuration, with available data rate of 9600 baud.
Environmental
Temperature: Stated accuracies maintained from –40°C to +80°C.
Humidity: Stated accuracies are maintained up to 95% relative humidity (non-condensing).
Fungal Resistance: A conformal coating is used on the printed circuit board to inhibit fungal growth.
Transient Protection
High Voltage: All input and output terminals will withstand 1500 V ac to chassis or instrument ground for one
minute, for all terminals to ground with a leakage current of less than 25 mA. Input and output circuits are
electrically isolated from each other, from other circuits and from ground.
Surge Withstand Capability: All input and output circuits are protected against system transients. Units
pass all requirements of ANSI/IEEE C.37.90.1-1989 defining surge withstand capability.
Radiated Electromagnetic Withstand Capability: All units are protected against electromagnetic radiated
interference from portable communications transceivers.
Electrostatic Discharge Sensitivity: Per IEC 1000–4.
