Gain Potentiometer

(POT)

POT 1: Display contrast adjustment

POT 2: Does Not apply to PID, not used Do not adjust

POT 3: Does Not apply to PID, not used Do not adjust

Visual Alarms

LED indicators:

Power / Fault Indicator LED, Green / Red

Alarm (3) Indicator Red LED, user adjustable

Magnetic Switches

ENU

: Advances the instrument display through menus (Zero, Span, Exit)

ELECT

: Selects the Zero, Span, Exit menu or sets proper calibration values for Zero or Span

Sensor

For sensing gas at

PPM

Magnetic switches control the instrument maintenance functions. The switch locations are indicated by M

ENU

and S

ELECT

. A

magnetic field pulse is applied by momentarily putting the end of the magnet in proximity to the switch and then removing it.

Referred to as tap. Since the magnetic field penetrates the window, the enclosure cover is not removed in order to perform

calibration.

Three alarm points are preprogrammed into the EX-5185 sensor/transmitters. At each alarm point, an LED on the front panel

is activated. These internal alarm settings are independent of the 4-20mA output alarm values that can be set at a controller.
