Trip Points: The PG10 can be congured with dual relay trip-point outputs.
The relays are SPDT mechanical in form. Each trip point (T1 and T2) can be
congured to perform one of six different logic functions as described below
and on the chart on the next page.
NOTE: The or icon will appear in the upper left area of the
display whenever the associated trip point is active.
Trip Relay Output Types (T1TYPE or T2TYPE): determines the logic
function of the output relays (see chart on next page).
“Type 0” or Normally Closed setting will close the trip relay whenever the
pressure is less than the Trip Pressure setting.
“Type 1” or Exclusive setting will close the trip relay whenever the pressure is
less than the Trip Pressure or greater than the Trip Pressure + Trip Window.
“Type 2” or Normally Closed with Hysteresis setting will close the trip relay
when the pressure drops below the Trip Pressure. Once closed, the trip relay
will remain closed until the pressure becomes greater than the Trip Pressure +
Trip Window, at which point the trip relay will open. Once open the trip relay
will remain open until the pressure once again drops below the Trip Pressure
setting.
“Type 3” or Normally Open setting will close the relay whenever the pressure
is greater than the Trip Pressure setting.
“Type 4” or Inclusive setting will close the relay whenever the pressure is
within the Trip Window pressure range (greater than the Trip Pressure, less than
the Trip Pressure + Trip Window).
“Type 5” or Normally Open with Hysteresis is used for pump up applications,
or for a low level alarm with hysteresis function. This is the opposite function
of the Type 2.
“Type 6” Trip Disable
