[+] Exhaust Pressure: Tests for presence of a vacuum on the exhaust pressure port;
estimates the vacuum that can be achieved in approximately 20 seconds.
[+] Regulator: Pass/Fail test of each reed valve in the regulator for minimum pressure
change. Note: Run this test only with 0 psig on the REFERENCE pressure port.
Supply and/or exhaust pressure is required.
[+] Internal Leak: Isolates
PCS 400
internal pressure at a selected value, then displays
pressure change.
[+] System Leak: Same as above except the output valve (L3) is opened to check for
leaks in the full internal and external pressure hookup.
[+] Display: Cycles a series of characters through all display elements.
[+] Keypad: Display echoes each key press until [CE] or [2nd] [any].
[+] Solenoids: Pass/Fail test of the integrity of each solenoid valve coil, L1 through L6.
(See text under ‘Solenoid Valves Test’.)
[+] Manual Valves: User can actuate manifold solenoid valves separately or in any
combination. (CAUTION: See text under ‘Manual Valves Test’.)
[+] Program: Test to determine that program checksum is correct. The data returned
by this and the following test can assist a factory engineer in diagnosing a problem.
[+] Program Memory: RAM test; displays RAM sections and checksums. Diagnostic
tool for factory engineer.
[3] LIMITS Allows the operator to define limits and setup options on certain items
selected from the following menu:
[=] Active Transducer: Displays SN, Address and FS of any transducer in the system,
and selects which is active or
AUTORANGE
if multi-range system
;
default is the
primary transducer at address 00. (See text under ‘Transducer’.)
[+] Control Limits Setup: Select control mode and set limits.
[=] Control Mode, select normal or rate
[=] Control Pressure (Rate): Set Rate for units/sec.
[+] Control Pressure (Normal) minimum: User sets lowest control pressure:
default is 0 psi.
[+] Control Pressure (Normal) maximum: User sets highest control pressure:
default is FS of primary sensor.
[+] Filter: Exponential smoothing of pressure reading.
[=] Window: Enter pressure value in the measurement units to be included in
the filter; ex: 0.001 = +/– 0 .001 psi; default = 0.025% FS.
[+] % Average: Enter 0 to 99% (Reading = last read * (%) + current read *(1–%));
default = 90%.
