monitor screen) and the input is off (requires manual reset of E-
Stop button).
Fluid Temperature Safety (I44): The fluid system temperature safety input is used to indicate that
the fluid temperature limit has been exceeded (LC chambers).
This input is active high, i.e., the input must be on in order for the
alarm to be indicated. When active (input on), the EZT shuts
down the chamber until the alarm is acknowledged (silence
button pressed on alarm monitor screen) and the input is off
(requires manual reset of limit device).
Fluid Pressure Safety (I45):
The fluid system pressure safety input is used to indicate that the
fluid system has exceeded maximum operating pressures (LC
chambers). This input is active low, i.e., the input must be off in
order for the alarm to be indicated. When active (input off), the
EZT shuts down the chamber until the alarm is acknowledged
(silence button pressed on alarm monitor screen) and the input is
off.
Fluid Flow Safety (I46):
The fluid system flow safety input is used to indicate that the fluid
system has proper flow (LC chambers). This input is active low,
i.e., the input must be off in order for the alarm to be indicated.
When active (input off), the EZT shuts down the chamber until
the alarm is acknowledged (silence button pressed on alarm
monitor screen) and the input is off.
The EZT has a built in time delay to disable the low flow alarm
until the pump has had a chance to start and begin moving fluid
(5 seconds). If the input does not turn on within the start delay
period, the alarm will be activated.
Power Failure(I47):
The power failure input is used to indicate that there is a primary
power failure to the chamber. When the chamber is equipped
with a battery backup option for the control circuit, it allows the
EZT to send out an alarm message over its network interface to
alert operators of the power outage. When main power is
restored, the EZT will automatically restart the chamber.
