Normal Operating States

This section details the four normal compressor states which the compressor may be in while a shutdown condi-
tion has not been annunciated.

3.9.1

Stopped Description

This mode of operation indicates that the compressor is not running and automatic start is disabled. While the
panel is in this mode, the red

STOP

button will be solidly illuminated.

3.9.2

Starting Description

This mode of operation indicates that the compressor is in the process of starting. During this period, the com-
pressor will unload to its minimum position. The compressor will remain in this mode as long as the conditions
required for the compressor to start are not met and the compressor has not entered a shutdown condition.
While the panel is in this mode, the green

START

button will be blinking.

The starting sequence follows the steps displayed below:

1.

Check Oil Pump Circulation (optional)

During this step, the panel will check that the oil temperature is greater than or equal to the value of the

Oil

Pump Circulation Temperature Set Point

. If the oil temperature does not meet this condition, the oil pump will

run to attempt to bring the temperature reading up to the appropriate value. If the temperature has not
reached the selected value after a period of time specified in the

Oil Pump Circulation Shutdown Timer

parameter, a shutdown will be annunciated. This step will only be displayed if the

Oil Pump Circulation Mode

parameter is set to

Temperature

.

2.

Check Drive Conditions

During this step, the panel will check that the time periods specified for example in the

Motor Start To Start

Timer

and

Motor Stop To Start Timer

parameters have elapsed.

3.

Check Oil Drain Timer

During this step, the panel will check whether the compressor must be drained of oil before being permitted
to start. If the oil must be drained, the compressor will wait until the time period specified in the

Oil Drain

Timer

parameter has elapsed.

4.

Check Control Signal Cycling

During this step, the panel will check the conditions of the compressor to ensure that the control value is in a
valid state to start. This step will only be displayed if the

Automatic Start Stop

parameter is set to

Enabled

.

5.

Check Permissive Start

During this step, the panel will wait for the permissive start signal to become energized.

6.

Check Pump Down Build To Pressure

During this step, the compressor will wait until the compressor suction pressure has risen to an acceptable
value. This step will only be displayed if the

Pump Down Mode

is set to

Automatic

in the configuration.

7.

Check Discharge Check Valve

During this step, the panel will check to ensure that the motorized discharge check valve, if applicable, has
opened within an acceptable period of time.
