Start Out Two sides of a normally open relay. Contacts are pulsed closed for
Identical to Pin 8 50 msec to signal start run when either of the following occurs:
C
If Pins 3 & 4 (Remote Configuration In) are not connected, the relay is
pulsed when is pressed.
C
If Pins 3 & 4 (Remote Configuration In) are connected, the relay is
pulsed when the oven temperature program starts.
Relay contacts are rated at 10 W, 0.5 A, 200 V dc maximum resistive load
only; 0.4 msec bounce.
Pin No.
11
Ground Ground pin.
Pin No.
12
Remote Ready In TTL input; expects a relay closure (connecting Pins 11 & 12) by an exter-
nal device if the device is not ready.
C
If a not ready closure is read, the HP 5890 NOT READY LED is lit and
a display
is generated. The NOT READY condition is also reported to the INET
system (if used).
C
The external device is assumed to be ready when the closure is
removed (disconnecting Pins 11 & 12).

Function Description
EQUIB TIME
Pin No. 5 & 6 or 5 & 9
Ready Out Two sides of a single-pole, double-throw relay; ready is signaled by the
contacts opening (Pins 5 & 6), or by contacts closing (Pins 5 & 9). Ready
occurs when the following conditions are met:
C
The HP 5890 is not in a run.
C
The oven is both on and at setpoint.
C
Oven has elapsed.
C
All heated zones that are on are at setpoint.
C
All detectors assigned to output channel(s) are on.
C
If INET is used, other devices on the loop signal ready.
C
No FAULT:s have occurred.
Relay contacts are rated at 3 W, 0.25 A, 28 V dc maximum resistive load
only; 1.2 msec bounce.
